The LiquidGeneration blog has posted a clip from last night's Late Show tribute to Johnny Carson, where a former Tonight Show producer told David Letterman that Carson almost snapped because one of the Charlie's Angels cast was incredibly stupid. The producer wouldn't name names, and said it wasn't one of the original Angels, but one of "the replacements"—leaving it up to interpretation whether he meant someone from the latter days of the television show (probably) or someone who would go on to star in the seizure-inducing McG movies (less likely). Liquid Generation thinks he was talking about Drew Barrymore, but really, don't burn too many brain cells over this one. The best part about timeless debates like "Who is the stupidest Angel?" is that there's not just one correct answer.
