British comedian David Walliams has vowed to give up his favourite party trick of pulling down a star's pants in public - because he's mortified at embarrassing Mark Ronson with the prank.
The Little Britain funnyman loves to surprise his pals by calling them onstage when he's presenting an event for U.K. charity Comic Relief and then yanking their trousers down.
He pulled the stunt on superproducer Ronson at a venue in London in 2009 - but he's now promised to quit the practical joke because the DJ was so upset at being targeted.
Walliams tells Britain's Buzz magazine, "I don't think Mark knew quite what he was letting himself in for. I have apologised profusely to him many times since. But he's Mr Cool. He didn't really need to have his trousers pulled down by me. I think maybe it's time for me to move on and not pull down any more people's trousers onstage."
