The Americanization of Machiko - August 4, 1953 - S2-E3
Factual error: In the scene where the guy is telling Machiko about the major league teams that wanted him, he mentions the Indians, Yankees, and Orioles. The episode is set in 1953 and the story is from before World War II. While there had been a minor league team called the Orioles up to that point, there was no major league team called the Orioles until 1954.
Maybe Baby - March 11, 1963 - S2-E20
Continuity mistake: At one point when the police are chasing Sam, the car has a Sheriff's star on the driver's side door; however, when Sam drives into Clayton, no star is to be seen.
All Americans - November 6, 1962 - S2-E14
Continuity mistake: In one play during the montage sequence of the championship game, the quarterback for the Jaguars (Sam) is number 15 - but he wears 12 throughout the rest of the show. This is Sam, because Al later tells him to quit, so he's been playing the whole game.
Maybe Baby - March 11, 1963 - S2-E20
Continuity mistake: When Sam is talking to Al in the store (while looking at car seats), Al checks on Margaret Dalton and holds the handset at chest level. The shot switches to Sam down on his knees and it's at his face level (about Al's waist). Then the shot switches back to Al and the handset is again chest high.
M.I.A. - April 1, 1969 - S2-E22
Factual error: Though this episode takes place on April 1st, 1969, a freshly-painted sign in the park contradicts the date. In the scene with the hippies in which Sam is disguised as a meditating guru, the huge sign just behind him touts the San Diego Centennial Celebration - in 1968. (00:16:00)
Good Night, Dear Heart - November 9, 1957 - S2-E17
Continuity mistake: At the end, when Sam is at the graveside, snow is falling and a close-up shot shows Sam covered in snow, but the wide angle shot shows little to no snow on him.
So Help Me God - July 29, 1957 - S2-E9
Factual error: At one point when Sam is visiting Delilah in the courthouse he is hugging her and the Sheriff guarding the door comes in and sees them. As the sheriff is leaving, he has a patch on his arm that says "County Sheriff." As this episode took place in Louisiana, there would only be Parish Sheriffs, not a County Sheriff.
Blind Faith - February 6, 1964 - S2-E5
Factual error: In the opening scene it is 1964 in New York City. A shot through Brooklyn Bridge shows the World Trade Center towers in the background. The Trade Center was not started until 1968 and not completed until 1973.
Her Charm - September 26, 1973 - S2-E15
Continuity mistake: The FBI agent's car is riddled with bullets in the opening scene. A few shots later, the same car rounds a corner during the chase, and all the bullet holes have disappeared. (00:03:30)
Good Night, Dear Heart - November 9, 1957 - S2-E17
Audio problem: When Sam and the Sheriff are on the dock the Sheriff is talking through a shot into the next one, except his mouth isn't moving during the last seconds of his line.
Her Charm - September 26, 1973 - S2-E15
Audio problem: When the two bad guys are chasing the girl through the dark forest, one says "it's too dark," the girl screams, and the other says, "who needs light?" - but both say these without moving their lips.
Her Charm - September 26, 1973 - S2-E15
Continuity mistake: After the bad guys attack the laundry truck and the girl starts throwing bags out of the truck, one sees in the close up shot a bullet-ridden gray door, but in the wide angle shot it's a pristine brown door.
M.I.A. - April 1, 1969 - S2-E22
Continuity mistake: Near the beginning, when Sam is undressing and Al is telling him who he leaped into, in one shot Sam is taking off his beaded necklace and in the next his necklace is off and he's taking off his belt, but Al continues the sentence so no time passed during the cut.
Pool Hall Blues - September 4, 1954 - S2-E18
Revealing mistake: After Al comes back when the power is turned on, Sam wins a game, breaks for the next and then we see a wide angle shot and the noise is made when Al shows Sam where to shoot. But the beam doesn't appear, even though the shot is seen by viewers.
Sea Bride - June 3, 1954 - S2-E21
Continuity mistake: At the end when Sam punches out the bad guy, there is not a white piece of trash stuck to the back of his left shoulder. Two shots later, there is a white piece of trash there.
M.I.A. - April 1, 1969 - S2-E22
Audio problem: When Sam, dressed as a guru, is talking to Al about Beth, Al calls the lawyer a "scuzzbag" but he mouths "scumbag." Guess it couldn't get past the censors.
Leaping in Without a Net - November 18, 1958 - S2-E19
Continuity mistake: In practice, when Sam's sister tries to do the triple and he misses her, the wide angle shot shows that she is already below Sam's arms when she reaches out. But when it cuts to a close shot, she is able to almost catch his arms.
Another Mother - September 30, 1981 - S2-E13
Revealing mistake: When Sam and Al are in the station wagon pursuing the van, both Sam and Al's reflections are visible on the wagon's front hood. Al, as a hologram, shouldn't have one and Sam's reflection should be as Kevin's mom.
Leaping in Without a Net - November 18, 1958 - S2-E19
Continuity mistake: Throughout the show, the big top changes from one with many blue stripes on the ceiling, to one with a couple of blue stripes and a dark center, and back again.
Pool Hall Blues - September 4, 1954 - S2-E18
Continuity mistake: After the bad guy tries to hit the granddaughter with the pool cue, Sam grabs it. In the wide angle shot it shows Sam's left hand about 6-8 inches from the middle (where the dark wood inlay is), but in the next close-up shot, his hand is only about 2 inches from the middle.
Chosen answer: Per the Quantum leap page at http://www.scifi.com/quantum/episodes/season5.html. 8 August 1953: An enigmatic leap lands Sam in a Pennsylvania tavern, as his own grown self on the day of his birth. As Al and Gushie work frantically to locate him, Sam befriends a wise bartender (popular character actor McGill, who'd appeared in a different role in the very first "leap") and a group of coal miners. As a host of familiar-looking faces pass through the bar - with different identities than Sam remembers - Sam ponders his life of leaping with Al the bartender, who tells Sam he controls his own destiny. Pressed for more, Al the bartender simply shrugs and says, "Sometimes, 'that's the way it is' is the best explanation." Sam realizes he must right at least one more wrong before he can go home, and leaps back to tell Al Calvavicci's wife Beth (from "M.I.A.") to wait for Al, who will survive Vietnam and come home to her. The closing title cards state that Beth and Al have four daughters and will shortly celebrate their 39th wedding anniversary ... and that Sam Beckett never returned home.
