I'd get a beer with Larry David and Ricky Gervais, both of who are polar opposites. With LD, I would relate to an entire conversation that was riddle with nothing but sarcasm. With Gervais, who wouldn't want to have a beer with someone that finds everything funny? I'd also echo Mac's choice with Colbert as well.

Believe it or not, but I'd also get a beer with Heather Graham and be content just to have a conversation with her.
