Talladega Nights is freakin' HILARIOUS. Highly recommended. Ferrell's great, of course, but it made me see Sascha Baron Cohen in a new light, since I think "Ali G" is one of the UNfunniest characters, like, ever.
Hip soundtrack too -- you might expect a NASCAR comedy to have Toby Keith and the like, but Ferrell and his director opt for Steve Earle. Not to mention the Best Use of Pat Benatar in a Movie since "Invincible" was in Legend of Billie Jean.
