That old egg-on-the-sidewalk thing is so last summer. Instead, mix up a batch of cookie dough, then proceed as follows:
Set the sections of dough several inches from one another on a standard cookie sheet. Place the cookie sheet on the dashboard of a minivan without tinted windows. Drive to downtown Phoenix on the hottest day of the year. Bake for two to four hours at 116° (47°C). Make sure news media are on hand.
Caution: Product will be hot.
