Surprisingly, the most shocking comment at Charlie Sheen's Comedy Central Roast on Monday night wasn't about hookers, blow or boozing  - or even about Charlie Sheen himself!

Comedian Amy Schumer managed to jack the distasteful factor up a giant notch with a controversial joke about deceased Jackass star Ryan Dunn that went down like a lead balloon with his best friend Steve-O, but despite the backlash, the little-known comic exclusively told RadarOnline.com that she has no regrets.

"If anyone feels offended then they are justified but I don’t think it was out of line. It was not my intention to offend but I stand by my joke," Schumer said. "It’s a roast and we’re going for the jugular. It was a joke about Steve-O and not about Ryan," she went on to explain. "I hope people understand that."
