Film ID. The mummy of Oughtnotten?

ISTR a mummy in a film being named Oughtnotten. I thought it might have been a Three Stooges film, but I remembered that that one was was called Rootentooten.

Was there, in fact, a film that featured the mummy of Oughtnotten? Or did I make it up?

There’s an Ahkenaten and I’m pretty sure it’s been used a couple times in films.

The Egyptian features a living Akhenaten, but not his mummy.

Unless it popped into my head on its own, it was in a comedy film and was a play on Ahkenaten – ‘Ought not (en)’.
