Back in 1990s, when "Happy Days" was still popular, Kurt from Long Island asked me to call him Chachi. He did look a little like Scott Baio.
My response, Sure if you stop wearing t-shirts and jockey shorts when we meet that's what Scott Baio would do.
He agreed, and from then on took all his clothes off a few seconds after ringing my door bell. "Hi, Chachi."
