After a recent video surfaced comparing Amy Schumer's material to other comedians' work, Schumer went on Jim Norton's SiriusXM Radio show today to deny any allegations of joke theft. "I wanted to come and talk to you about [these accusations] and clear my name, because I would never ever do that and I never have," the comedian said, adding that she is "literally going to take a polygraph test and put it on my show this season."The video collects allegations — some of which surfaced this weekend, others older — that Schumer copied material from Patrice O'Neal, Tammy Pescatelli, Kathleen Madigan, and Wendy Liebman. Talking to Norton, Schumer said that she had not seen any of their jokes before she performed her own and that any similarities were a result of parallel thinking, not plagiarism. She previously addressed similarities between O'Neal's punchline and a line from her stand-up special on Twitter last fall.
