From The Huffington Post:
Scarlett Johansson showed up on Leno Wednesday with a bad cold she says she caught from "The Spirit" costar Samuel L. Jackson.
With a nasal voice and a throaty voice, Johansson said she thinks her cold, as it's a celebrity cold from Jackson, has value. Leno decided to help monetize the germs.
Johansson gave a tissue a honking blow and bagged it for Leno to put on ebay for the charity USA Harvest.
"And you got some lipstick. And snot!"
She signed the bag and the auction can be found here. Bids at 9 am topped $2,025. Well, at least it's for charity and in the holiday spirit...
