Mountain Man Toothpicks are a 100% real.
I've also seen whale and walrus oosiks (penis bones) carved into flutes. They are a novelty item you have your friends try to play a tune on by blowing into one end. You tell them they are an ancient tribal musical instrument. (You should see there face when you tell them what they are really blowing on!!).
I couldn't find a link, but here is a beer sign talking about them:
