Oscar and Criss, now in their eighties, first met in grade school.

Their relationship now is playing cards, playing jokes and making bets.

One day Oscar calls Criss and says, "I bet you that mine is longer soft than
yours is hard. A thousand dollars."

Criss replies, "How can that be? If you know anything about biology you..."

Oscar interrupts, "I called for a bet, not a lecture. Mine is longer soft
than yours is hard... a thousand dollars... YES OR NO?"

Criss says, "OK OK! I'll take that bet. How long is yours soft?"

Oscar answers, "Eleven years."
