Groucho marx quote?

Question

When, and why, or to whom, did groucho marx say: I've had a wonderful time, but this wasn't it."

Answer 1

Although many of Groucho Marx's quotes are attributed to movies, the one you are searching for is labeled as unattributed (the majority of his quotes are).  Most likely it was simply part of his comedy routine and not necessarily said to anyone.
