I am fine with adult humor, blue comedy, whatever you want to call it, but there's a couple of comedians that make me switch the channel whenever I'm listening to XM Comedy in the car. This guy is one of them, and another is Doug Stanhope. Over the top gross-out comedy to me just isn't funny. It's formulaic and unimaginative.
There's also a new breed of female comedian, whose stock and trade is this "we're even nastier than men" comedy. Again it usually just comes off as lame. A lot of times they use abortion as subject matter and seem to relish in their glib treatment of the subject. Amy Schumer is one of these. I've watched a few episodes of her show. Some of it is not bad, but most of it is just some variation of her "I'm such a jizzbucket I need to get this thing scraped out" schtick.
