Jim Carrey has been hailed as the "funniest man on earth" by director Judd Apatow.
The director of Knocked Up and This Is 40 once toured as the opening act for Jim during his stand-up comedy days and paid homage to him in Vanity Fair magazine, saying The Mask star "will always be king".
Judd wrote: "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."
Jim, 50, recently splashed the cash to hire a private boat for the cast and crew of his new film Kick-Ass 2 and took them on a guided tour of all the sights along the River Thames.
The Dumb And Dumber star apparently kept co-stars - including Chloe Moretz, Nicolas Cage and Aaron Taylor-Johnson - entertained with his made-up history of London and his own rendition of The Proclaimers' hit I'm Gonna Be (500 Miles).
