This is why I am never in the front-row of a comedy show. So horrifying!

Super producer and Gucci sneaker designer Mark Ronson was given a bum deal at a charity show in London after British comic David Williams wrestled him to the floor ripping off his pants and underpants.

Ronson was attending a Concert For CARE show at the O2 Academy in London Monday night. David Williams performed a stand-up set at the event and – in the guise of his comedy alter-ego Des Kay – invited his unsuspecting celebrity pal on to the stage. Ronson was horrified when the comedian grabbed his crotch and then threw him to the floor, pulling at his trousers as the musician desperately fought to protect his modesty.
After successfully removing Ronson’s underwear and baring his backside to the crowd, Williams exclaimed, “It’s just a bit of fun, Mark!” before allowing the visibly furious star to get to his feet.

So not funny
