Looks like most of my favorites have been tossed out there already, Carlin, Hedberg, Izzard, Wright, I also really liked some of the stuff Bill Cosby has put out over the years.
Another favorite isn't exactly stand up but I usually found myself laughing anyway is Henry Rollins when he does a spoken word gig. I'd post some links but his language is, shall we say.... colorful? But I've always found him to be really entertaining.
