Plot hole: Greg suddenly wears Jack's "breast" during the "monkey business" scene with a crying LJ. But the only time we see it is in the RV which Jack would most likely have kept locked up. How did Greg get ahold of it?
Meet the Fockers (2004)
1 plot hole - chronological order
Directed by: Jay Roach
Starring: Robert De Niro, Ben Stiller, Dustin Hoffman, Barbra Streisand, Blythe Danner, Teri Polo
Continuity mistake: Jack drops the two vials into the Tom Collins glass, while in the bathroom. At the hand-off, when he places the drink on the tray, there are no vials in the glass - there is no ice blocking them from view, just a skewer holding a maraschino cherry, a wedge of lemon, and a straw - no vials. Even Jack can't make the two vials invisible. (01:23:40)
Pam Byrnes: In a few weeks, I'm not going to be Pam Byrnes. I'm going to be Pamela Focker.
Greg Focker: Or Byrnes-Focker, we haven't totally decided yet.
Pam Byrnes: No, no, no, I'm going to be Pamela Martha Focker. I know how that sounds but that's the name I'm taking.
Trivia: Near the start of the movie, when Greg & Pam are on the plane, the stewardess who asks Greg if he wants help with his case, is the same one that he shouted at near the end of the first movie.
Answer: Muskrat is a "code word" they use to remind Jack to keep his temper under control.
