I am surprised that no one has mentioned one of my favorites, Mae West.
She played both a hooker and a madam in many comedic films.

In Mae West's first movie scene, a hat check girl exclaims, "Goodness, what beautiful diamonds." West replies, "Goodness had nothing to do with it, dearie."
Other famous Mae West quote: "Why don't you come up and see me sometime, Big Boy."
And my favorite quote: "When I'm good, I'm good. When I am bad, I'm better."
