Does anybody remember the show where somebody's birthday is forgotten, and at the last minute somebody shows up with a birthday cake that says "Happy Bar Mitzvah Sheldon"? This is driving me crazy. Thanks for your help.

i think that was a happy days ep and they got a cake at the last minute that said happy bar mitzvah herbie

This response is about 10 years late, so you've likely gone crazy long ago, but the correct answer is that it's from an episode of "The Odd Couple." I can't recall the exact details of the story, but I think it was bought at a discount (because the person who ordered it never picked it up) and used to celebrate Murray The Cop's birthday.
