George was a staff writer on the Comedy Central Roasts of Justin Bieber, Rob Lowe, Bruce Willis, and James Franco.

And even before to those gigs, George had written jokes for the past 6 Comedy Central Roasts for the Roastmaster General Jeff Ross, including the Roasts of Charlie Sheen, David Hasselhoff, Roseanne Barr, Donald Trump, and Joan Rivers.

In Canada, the Sheen Roast was the highest-rated non-sporting event ever on cable television.

Here is an interview George did in Chicago discussing what happened behind the scenes of the Roast of Rob Lowe.

George also contributed to the untelevised Friars Club Roasts of Quentin Tarrantino, Boomer Esiason, and Betty White, and the private roast of Richard Branson. 

George was the main writer for Comedy Central's official Trump Roast internet pre-show "Jeffrey Ross' Fireside Chatroom"  

And George even contributed jokes to Charlie Sheen's "Violent Torpedo of Truth Tour".  When the tour started to get bad reviews, Charlie invited Jeff Ross to come on stage and roast him in a couple of cities.  And of course, George was hired to write many of the jokes.  Many claim this saved the tour.  Watch for yourself here...
