May is National Smile Month -- to celebrate I had everyone do a "Knock Knock" joke for you!
You remember the jokes as a kid or play them with your child. The standard format has five lines:
The joke-ster: Knock, knock!
The recipient: Who's there?
The joke-ster: A response, sometimes involving a name (Doctor)
The recipient: A repetition of the response followed by who? (Doctor who?)
The joke-ster: The punch line, which typically involves a "punnish misusage" of the word set up during the response (How did you know?!)
After the jump -- check our our corny fun!
