To be honest (and I suppose prudish) the funniest stuff was clean. I don't understand the attraction to the overt raw stuff. It's not funny, just shocking.
I saw the one of Jeff Foxworthy and realized that Comedy Central, or at least the comedians in these roasts, have lost the ability to distinguish "funny" from "offensive". For example: telling someone to "close their legs" is grade school shock humor, not prime time comedy.
