Chuck e Cheese token.
If you burn some black soot onto a pan because you forgot to turn the stove burner off when the broccoli was done steaming and the water all dried up, here's what to do:
1) Soak bottom of pot in soapy water, oven cleaner, or white vinegar (full strength).
2) Wait over night.
3) Scrape with a Chuck e Cheese token.
Clean pan, guilt-free junk storage of that Chuck e Cheese token you've been thinking about throwing away.
