Patton Oswalt. I’ve absolutely cried laughing at his two CD’s. Feelin’ Kinda Patton is the stronger of the two, but Werewolves and Lollipops is close. I consider myself a bit of a standup aficionado, and frankly, Patton’s the strongest comedian out there right now.
The thing that really kills me about Patton is that he can do live, unprepared, off-the-cuff material that’s as funny as or even more funny than the stuff that he’s written and prepared. Check out the “ether frolic” part on Feelin’ and the part where he destroys a douchebag heckler on Werewolves.
