Who is this person?

I've never heard of him. But I've heard a few people on the boards mention him, sometimes in not a very complimentary way!

I figure he must be american? On Channel 4 in Ireland and UK we have "It's me or the dog", which I quite liked (SHOCKING how some pet owners and their pets behave). Unfortunately we moved house and didn't have channel 4 all last year, so only saw one or two episodes. Anyone know if it will be back?
