My jujitsu instructor told us some time ago during warmups (when we usually have casual class chats) that he met a guy who was being very pompous while talking to my instructor. The instructor asked him, “What do you do?”
The jerk said proudly, “I’m a rapper.”
Ever unimpressed by people’s egos, my instructor said irreverently, “Oh, you must be really busy around Christmas-time, then.”
He said the guy didn’t find it funny.
I thought it was hi-larious.
