Ever wonder what Katy Perry would look like as a chubby Jewish man?

Neither have we.

That didn’t stop the “Roar” hitmaker from donning such a disguise recently, in a video created to promote her new single, “Birthday.”

In the video, Katy dresses up as the world’s worst birthday party entertainers, including an aging Vegas showgirl, a drunk clown, and a bar mitzvah DJ.

Watch the clip above, but be warned–some of these costumes will haunt you!
