So in the interest in finding some new people to laugh with, I'm gonna post some of my favorite comedians, and I hope you do the same.
First on my list is Robin Williams, partly because he too is an avid biker and plays Warhammer 40k (Space wolves apparently, grrrr.), but also for his amazing ability to go on for a great length of time, about many things, and make them very funny. People have told me we share a comedic style, and he is my clown persona's mentor.
Following Robin, is Mitch Hedburn, King of the non-sequiturs. It was shame he died in 2005 from a drug overdose, but his jokes shall live on. Here is a wikiquote page of some jokes, although I would recommend that you watch some youtube video's first in order to pick on his style and delivery. Mitch Hedberg - Wikiquote
Finally I love Gabriel Iglesias, first because of his amazing taste in shirts. But he is comedian that moves around, I really hate comedians that just stand at the mic and talk. (Mitch is the exception) Yay for energy and crazy good sound effects.
