Who? Where? When?

Today, without any provocation I can think of, a phrase flitted through my mind, with almost no content attached, and I'm hoping somebody on my FL can identify its origin. I suspect that it came from a movie, or perhaps a television show. A cartoon?

In my head, this is what I hear: a gruff voice - an older man, probably, with a pseudo-German accent - bellowing "Enough is too much!"

Does that ring a bell with anyone?

Cela, Je N'aime Pas

Look, I like Nat King Cole's voice.

But whoever it is that suggested he try to sing songs in other languages - even partly in other languages - should have been taken out and shot.
