Reminds me of an old Steven Wright joke:
He said when he was in college, his apartment had a switch on the wall but he couldn’t figure out what it did.
But when he was bored or thinking, he’d flip the switch. Up, down, up, down, up, down, up, down, up, down, up, down, up, down, and on and on and on.
He said about two years after he moved in he got a letter from a woman in Germany.
She wrote: “STOP IT!!!”
