Knock, Knock. Who's there?

So we got to talking about Knock Knock Jokes, and the suggestion came up that the right punishment for telling a knock knock joke would be to get whatever the subject of the joke was rammed up your ass a week and 3 days later. For instance, you tell those horrible jokes about the bananas. 5 knock knock jokes about bananas in a row, and then one about an orange. A week and 3 days later, you'll be shitting out a smoothie.

Knock Knock
Who's there?
K-Mart

"Naw Bobby, don't go on with that one. That's gonna hurt."
"Hey, Where's Bobby? We haven't seen him in about a week..."
"Well he told this knock knock joke a few days ago, and now he's at K-Mart"
"At K-Mart?"
"More like...around....K-mart. We suspect it's the Arkansas one....you know, that there big un."
