They both have just gotten increasingly old. The acts aren't funny. Not very many people want to see lame ass jokes by lame ass comedians that have mostly been stolen.

Mencia has the same overplayed jokes as every other Hispanic comedian, yet he finds a way to destroy them. His show is an abomination to COMEDY Central. Dave Chappelle could pull off the race jokes, but Mencia is just awful.

Mitch Hedberg, Zach Galifinaks, Lewis Black, Dave Chappelle, and Mike Birbligia are all great.

Mitch Hedberg is my favorite of all.
