Scarlett Johansson is not one to waste.

Maybe that’s why the "Match Point" star and wife of actor Ryan Reynolds is selling her used tissue on eBay for charity.

It’s gross, but true.

During an appearance on “The Tonight Show With Jay Leno,” she told Leno that her "Spirit” co-star Samuel L. Jackson had given her his cold.

She humbly added that the cold was the union of two big stars, so the tissue undoubtedly had high value.

So ScarJo decided to auction off the tissue Leno gave her, after using it, with the proceeds going to USA Harvest, a charity Johannson selected.

If you are interested in bidding, you better be prepared to drop a hefty chunk of change. The tissue has already nabbed offers for more than $2,000!
