I remember reading a story on Groucho in CA...I'm paraphrasing, but...
He was in Rome, walking around smoking one of his favorite Dunhills...and he was bumped by a passerby and his cigar fell in a puddle.
Groucho said, "Jesus CHRIST!"
With that, the man who had bumped him - a priest, turned and said "congratulations, Groucho...you just said the secret word."
