Amy Schumer denies stealing jokes: 'That would be so stupid for me to do that'

Comedy superstar Amy Schumer is vehemently denying claims that she stole jokes from several other comedians -- including Wendy Liebman, Tammy Pescatelli, Kathleen Madigan and the late Patrice O'Neal.The accusations against the Emmy-winning comedian surfaced on Twitter over the weekend, prompted by a tweet from Liebman (since deleted, but captured here by Buzzfeed) that said she was "done with social media" thanks in part to "Amy Schumer doing 1 of my best jokes on her HBO special."
