If you've watched Curb Your Enthusiasm, you often wonder if Larry David is actually as irascible and bad-tempered in real life as he is on the show.

Granted, an interview on a late-night talk show isn't all that representative of real life, but it's as close as we're going to get - and, yes, Larry David is just like he is on the show. In fact, he's even more angry than you'd imagine and less likely to give an answer than complain about being asked it in the first place.

It's always good to know there's an authenticity when people play certain roles, and Larry David's got it in spades.

Take a look.
