My friends and I play this game that we like to call "Is that Matt Damon?" which all stemmed from watching Departed. And, basically, anytime we're watching a movie someone will very sincerely ask if X actor that is definitely NOT Y actor is said Y actor.... like,

*watching Departed - Mark Wahlberg comes on the screen*
Me: Is that Matt Damon?
Friend: No.
Me: That's definitely Matt Damon.

And then we argue until someone realizes I'm just trolling them and I know it's not Matt Damon. I'M SORRY! THIS IS REALLY CONFUSING! But it's super fun and people get SO MAD trying to convince you that said actor is NOT Kevin Spacey/Chris Pratt/Bradley Cooper, etc etc...
