VIDEO : Steal Jokes? Amy Schumer Will Strap on a Polygraph to Prove She Doesn't Do That

"I will literally take a polygraph." That's what Amy Schumer is saying in response to accusations that she steals jokes. Schumer appeared on the radio with fellow comedian Jim Norton on his SiriusXM advice show Wednesday. This week, three comedians ? Wendy Liebman, Kathleen Madigan and Tammy Pescatelli ? took to Twitter to discuss alleged similarities between their jokes and ones that Schumer has used in her Comedy Central series, Inside Amy Schumer, and the movie, Trainwreck.
