I discovered him on YouTube when I was searching for heckler videos. I know he's been to the UK but I don't know how big his following is there. His YouTube channel is full of clips of him dealing with hecklers at his various live performances, as well as a podcast and other informative videos for budding comics.
He now co-owns three comedy clubs. The most recent purchase was a place in Louisville, Kentucky that hired him back when he was starting out. They're giving the place a 100,000 dollar renovation and they have some big names lined up to perform there.
I'll be seeing him at the Hard Rock Café in Boston on the 1st and I really can't wait. Here's the link to his YouTube channel if you're curious.
