Dina Byrnes: Now Greg, you have a very unique last name. Um, we were curious, how do you pronounce it?
Greg Focker: Oh, just like it's spelled. F-O-C-K-E-R.
Dina Byrnes: F-Focker.
Jack Byrnes: Hmm, Focker. Hmm.
Trivia: Originally, the film was meant to be a vehicle for Jim Carrey. Among his contributions was Greg's surname, "Focker." Eventually, Carrey left the production, and Ben Stiller took the part.
