You might be slightly crazy if...

You attack a laundry stain with the words "The power of OxyClean compels you!"

You might be overeducated if you come up with a modernism "your mum" joke. Observe:

Your mum is a fish.

(Warning: You might be overeducated if you get the joke.)

Every time your 3 year old nieces play Ring Around the Rosie, your mind supplies "Black Deeeeaaaaaath."
