True story: I was having dinner at a friend’s house this evening, and a guy we both know called her on the phone with a riddle, specifically for me. He asked “What is a unit?”
“I give up,” I said, “What is a unit?”
“It’s a sweater you make yourself,” he said.
And that was it. He had called her house only so he could tell me that joke.
I thought it was a really funny joke, but my friend, she wasn’t so sure.
“Well,” I said, “at least we know he came up with the joke himself.”
“Why is that?” she asked me.
“Because,” I explained patiently, “If it’s a sweater you make yourself, then it has to be original material.”
