I just saw the preview for Step Brothers, starring Will Ferrell (as Brennan) and John C. Reilly (as Dave). I don't know that I need to see the whole movie, but this did crack me up:
Dave: Okay. Name your favorite dinosaur.
Dave & Brennan: [simultaneously] Velociraptor.
Brennan: If you were a chick, who's the one guy that you would sleep with?
Dave & Brennan: [simultaneously] John Stamos.
Brennan: Did we just become best friends?
