[Idiom] Make A Fool <Out> Of

[Samantha293]

a) "He made a fool of himself."
b) "He made a fool out of himself."

Is it possible that one is more correct than the other, or are they both okay?

They're both OK, but the first is better as out is redundant.

I'm rather pleased to see my understanding confirmed by a teacher! :-D
