I have all of Rodney Carringtons cds and recently have added the dvd of him performing at the majestic to the collection.
Mitch is also a classic, I like his bit about refried beans and fritos. "I wanna try fried beans, cause maybe their just as good and we are wastin time!"
Im partial to the singing comedians. Stephen Lynch espcially, Adam Sandler and here recently Bo Burnham.
As far as George Carlin goes, call me crazy but ive never really found any of his material funny.
