After ordering a milkshake, a man had to leave his seat in the restaurant to make a phone call. Since he didn't want anyone to take his drink, he took a paper napkin, wrote on it, "The world's strongest weightlifter," and left it under his glass. When he returned from making his call, the glass was empty. Under it was a new napkin with new writing that said: " Thanks for the treat!" It was signed, "The World's Fastest Runner."
