We take puns very seriously.
The Punboard is populated when someone replies to a pun they see on Twitter and tweet back with #punboard and #groan (which is good, like a groan of approval) or #sadtrombone (which is a vote of "come on now, you can do better than that").
The Punboard is a real-time leaderboard of who the top pun-makers are on Twitter. People get ranked up (punted) or down (punished) based on their Klown Score, which is like a Klout Score, but a lot more relevant.
Through a proprietary algorithm written by a PhD in CS (Clown Science), these #groans, #sadtrombones, number of votes and number of puns are put in a circus machine and out poops your Klown Score. The best Klown Score wins.
But you've got to stay on top of your game if you want to stay on top of our game.
