Judd Apatow thinks that Jim Carrey is the "funniest man on earth." The influential producer and director once toured as the opening act for Jim during his stand up comedy days, and while Judd acknowledges there are many talented comedians working today, he thinks Jim is still the best.

"When I was a stand up comedian in the late 80s, I used to open for Jim Carrey on the road. I would do my lame act and then he would come on and do the most energetic, inventive, uproarious set I had ever witnessed. I retired from performing as a result. He was and is the funniest man on earth. This is something we can all agree on. We can debate number two forever but Jim will always be the king," Apatow wrote in Vanity Fair.
