Many years ago, this joke appeared in an April issue of the Communications of the ACM (before the Cray 3 actually existed):
"Have you heard about the new Cray 3? It's so fast it can execute an infinite loop in about two minutes."
A coworker and I went out for lunch. Not realizing that I had already read the joke, he asked me, "So, have you heard about the new Cray 3?" I replied "Why no, how long does it take it to execute an infinite loop?"
Back at the office, he described this to our colleagues. Trying to recreate the event, he said to me, "So, have you heard about the new Cray 3?" In front of everyone else, I just said, "Why no."

"I hate you", he said.
