Marvelous Mrs. Maisel scene identification

I was trying to describe a really funny scene from MMM today to my wife, but couldn’t find it online. The scene is set at a children’s birthday party, where the parents have hired a well-known(?) magician. He clearly isn’t into it, and performs the funniest terrible magic show you’ve ever seen.

The problem is that in the most recent season another magician has entered the cast, and every search pulls up info about him. Does anyone have any idea which episode I’m thinking of?
