From seven years ago:
Went to an outdoor concert in San Diego where lots of middle aged and older people were dancing. At one point, they all started doing the same synchronized dance.
“I didn’t know this song had a special dance?” I said.
“It doesn’t.” My wife said, “That’s just a basic line dance. We never got divorced so you never had to learn about that.”
“So in an effort to attract a mate, everybody gets in line, does the same thing, and makes no effort to stand out from the crowd?”
