Banana Suit

[Ash]

My sister called me earlier asking if I knew the title of a movie.
She said it was a horror film and a guy in it was wearing a banana suit.
I have no idea what film she's thinking of.

Do any of you know what it might be?

It's not a film, but there's a Halloween episode of Bottom where one of the characters is wearing a banana suit. The other is dressed as the devil. There are also three smaller devils running around.
