WELL... lessee..
Gervais.
Lampenelli.
Any of the mexicans. Seriously.. I've never found a funny one of them. Even that one guy from the 80s who was in a slew of comedies and HBO specials. Something Rodriguez. Or lopez. At the risk of sounding racist.. DONT YOU HAVE ANY UNIQUE LAST NAMES?!? For fucks sake.. I cant tell you how many lopez/rodriguez/torres I've seen in my days. Anyway.
Milanokis.
Joel off MST3K (MIKE OWNS YOU! GTFO JOEL!)
Seinfeld (You're clever. You had a decent show with all those writers backing you. But your standup? It's like one of the mediocre seinfeld episodes without the variety of actors to help you.)
CARROT FUCKING TOP. Prop actors.. oh dear fucking gawd I hate them. Not so much Gallagher's old stuff, at least he threw in a dozen jokes between one-time use props.
That fat white guy that acts like a black guy. Something-Ray. Billy Ray? I dunno, but while he gets a few laughs.. he loses them with the delivery, accent and subject matter.
Will Ferrell. Seriously, stop making movies.
