Homeless Matt Damon and Psycho Val Kilmer Are ‘Best Friends’ with Katy Perry and Andy Samberg on ‘SNL’ [VIDEO]
If there's one thing Katy Perry and Andy Samberg taught us this week on 'SNL,' it's that the holidays are the time to spend with loved ones and 'Best Friends.' It's also the time to meet new best friends, even if they happen to be a homeless Mat Damon, who likes to steal socks, and "brilliant lunatic" Val Kilmer, who likes to huff gas fumes.
These four pals certainly go through a lot together in the just over two-minute digital short. After Damon loses Russian Roulette, however, Perry has enough and Samberg is left with Val Kilmer who brings back Abraham Lincoln.
Find out what other shenanigans these besties get themselves into.
