A guy is with a friend. He points to another guy down the street and says “Look, that’s the town idiot. I’ll show you. I do this every week”
He then hollers at the other guy
” Hey Kevin! Here, a gift for you, and you get to choose! One $20 bill, or five $1 bills?”
Kevin happily grabs the five notes and leaves. The guy laughs at him.
The friend happens to meet Kevin later and asks him why he picked the five bills. Doesn’t he know 20 is more than 5×1?
“Yes” replies Kevin. “But the day I pick the 20 he’ll stop giving me money”.
