A slice of pizza is in the stomach, waiting to be digested. Suddenly, a shot of whiskey barrels down. The pizza lets it pass in front of him.
A few minutes later, another shot of whiskey comes through. Courteously, the pizza lets it pass in front of him, too.
A few minutes later, a third shot of whiskey tumbles into the stomach. The pizza asks they whiskey, “What’s going on up there?”
“They’re having a really great party”, says the whiskey.
“Really? responds the pizza. “I think I’ll go up there and take a look”.
