Scarlett Overkill: Doesn't it feel so good to be bad?
Herb Overkill: Woah! These guys are pumped!
Scarlett Overkill: Maybe I'll settle them down with a bedtime story.
Bob the Minion: Bedtime story?
Scarlett Overkill: Once upon a time, there were three little pigs. The pigs encountered a big, bad wolf, who hired the three pigs to come work for her. One day, the pigs did something very stupid, so the wolf huffed, and puffed and she BLEW THEM OFF THE FACE OF THE EARTH! The end.
Scarlett Overkill: Work for me, and all this will be yours: respect, power...
Stuart the Minion: Banana!
Scarlett Overkill: ...Banana.
Scarlett Overkill: Do you know who this is?
Kevin the Minion: Uh... La cucaracha?
Scarlett Overkill: This is Queen Elizabeth! Ruler of England! And I really, really, really want her crown.
Chosen answer: The writers wanted to keep Gru's cameo at the end of the film a secret for the fans of the franchise. So, saying "42 Years B.G" (before Gru) in the trailer doesn't give the surprise away.
