Two friends with radically different political views are on their way to the polls on election day. One guy turns to the other and says "You know, we've argued about this for months, and we're obviously going to vote for different candidates. Our votes will cancel each other out anyways, so why don't we just call it a draw and go home instead?" Other guy agrees, they shake hands and part ways.
Another guy who overheard the conversation approaches the dealmaker and says with admiration, "That's a real sportsmanlike offer you just made!"
"Not really," guy says, "Just this afternoon I've already done this three times."
