The Late, Late Show host James Corden went on down to Western Kosher in Los Angeles. In a sketch similar to David Letterman’s Taco Bell pranks, Corden spent an afternoon working at this kosher grocery store, learning to carve meat and drive a forklift.

Corden is not Jewish but, as he explains in the video, “all my friends are [Jewish] and I’m practically kvelling at the thought.” The moment he dons a yarmulke, he starts singing a classic Chassidic niggun. (But the best part is when another employee and a customer join in with him.)

Fortunately, Corden stays away from any groan-worthy Jewish jokes, and all the laughs are at his own expense. He may not be cut out for working at the kosher deli, but he’s certainly welcome for Shabbat dinner anytime!
