I like some of Lenny Bruce's stuff. The whole martyr for free speech thing makes it hard to see him as something other than a tragic or pathetic figure, but I picked up a copy of the Sick Humor of Lenny Bruce, and it was good for a couple of laffs. With Carlin, having heard all the material several times since I was 9 or so, it's like crap you say in church without even realizing what you're saying anymore; it's lost all meaning.
Patton's Werewolves and Lollipops was the last comedy album I bought. I'm much more likely to listen to that and get more laffs out of it than TSHOLB. No, actually Rock, Rot, or Rule was the last comedy album I bought, but it hasn't shipped yet.
