I saw Jim Jefferies a few years ago on HBO. It was one of those late night comedy specials and I thought I was going to piss my pants from laughing. I ended up staying up in order to catch it again on the west coast airing.
He is loud and obnoxious. And he is Australian. For some reason, I should probably not like him, but I guess it is the fact that he professes to be an atheist. Or that he is hilarious. I am not sure. I tried to get into his show, Legit, but I just did not like it.
