Trivia: When Deadpool autographs the cereal box he signs it Ryan Reynolds.
Trivia: The two rednecks sitting on the back of the pick up truck when Cable arrives are played by Alan Tudyk and Matt Damon, whose makeup took 4 hours to apply.
Trivia: At the start of the scene where Deadpool and Weasel are recruiting the X-Force, they are looking at photographs of the applicants. The first photo shown is of Ruth Bader Ginsburg, an Associate Justice of the Supreme Court. A closer look at the photo will show that her superhero name is Notorious R.B.G. (00:53:55)
Trivia: A promotional poster for the PG-13 version of this film (Once Upon a Deadpool) was released as a parody of a painting commissioned by the LDS church called "The Second Coming." This was reportedly done in response to the state of Utah - known for the LDS church having unconstitutional influence over its state laws - fining a theater that served alcohol for showing the first film, alleging that it violated state liquor laws by serving alcohol while showing nudity or simulated sex.
Continuity mistake: In the final fight, Deadpool says to Cable "did you feel that too?" and there's no-one behind them at all. Cable moves forwards to kill a guy on the ground, and a fraction of a second later, as Deadpool says "only best buddies execute paedophiles together" an orderly has appeared in the background, who gets shot.
Answer: That's one of his superpowers, "Comic Awareness" (sometimes called 4th Wall or Medium Awareness). This is something that Deadpool has in the comics and was incorporated into the films. Other than being a framing tool and to be funny, I don't know if the creator, Fabian Nicieza, or any writers have said why they gave Deadpool that power.

Deadpool's trait of breaking the 4th wall appears to have been the idea of writer Joe Kelly, as Deadpool didn't break the 4th wall for the first time until Deadpool #28 in May 1999, more than 8 years after his debut.
