All hell breaks loose when the Byrnes family meets the Focker family for the first time.
 
No review.  Just a quote from the movie.
 
[the Fockers' outgoing message]
Bernie Focker: Hello, you've reached the Fockers. We're not around, so leave us a message. Goodbye. Roz, how the hell do you shut this thing off?
Roz Focker: I have no idea. Just press a button.
Bernie Focker: All right, I'm pretty sure it's off. Honey, you want a chimichanga?
Roz Focker: I thought they give you gas.
Bernie Focker: A little bit, but it's worth it.
Roz Focker: Yeah, worth it for you, but I'm the one that gets the fumes.
Bernie Focker: Honey, I'm in the mood for a chimichanga!
Roz Focker: So make a chimichang...[beep]
 
Nuff said.
 
FUN FACT:  The flight attendant, Kali Rocha, is the same one from Meet the Parents (2000). That is why Greg gives her an odd look when she offers to take his bag and be helpful.
