I understand that people collect unusual things... But I'm not sure if this is creepy or cool.

Back in the 60's, John Lennon had a molar removed and then gave it to Dorothy "Dot" Jarlett, his housekeeper (How did that conversation go? Here, have a tooth???).

Now, her son is getting ready to auction off the unusual memorabilia.

He told CNN, "She was very close with John, and one day whilst chatting in the kitchen, John gave my mother the tooth and suggested giving it to my sister as a souvenir, as she was a huge Beatles fan. It has been in the family ever since."

But if you're a tooth collector, be prepared to spend those pennies... Reserve price is set at $16,000 at Omega Auction House.
