On Jan. 30, 2013, Fred Norris gave one of the most convincing performances of his career as an entertainer — and this time it wasn’t behind a soundboard in the Howard Stern studio.

That performance, of course, was a cameo in an episode of “Law & Order: Special Victims Unit” sinisterly entitled “Criminal Hatred.” Fred played an apathetic smoke shop owner named Leon who had to answer to detectives Tutuola and Rollins after selling some merchandise to a customer whose identity didn’t quite match up to the credit card he used for his purchase. Here’s how Fred handled the encounter.

First he offered them a look of confusion.
