Possibly The Greatest Recipe In HistoryNot a recipe, actually, but cooking directions.
I saw in a magazine that if the temperature is 100F or higher, you can do the following:
1. park your car in the sun
2. roll up the windows
3. put slice and bake cookie dough on a cookie sheet
4. put the cookie sheet on the dashboard (with a towel underneath, to protect the dashboard)
5. Come back in 2.5-3.5 hours (depending on temperature).
You will (apparently) have fresh-baked cookies, ready to eat. I may gain 20 pounds this summer.
