Don't turn around. Even if they are four times your size.
A dwarf gets on an eleveator and pushes the button to go up. Just before the door closes, a hand comes through and opens the door. In steps a very large black man. The dwarf stares and says, “You’re the biggest man I have ever seen.” The man nods his head, and replies, “I’m 6’9”, weigh 259 lbs., and I have 16 inches, I’m Turner Brown.” The dwarf faints! After coming to, the dwarf asks the man to repeat himself. So he does. “I said, I'm 6’9”, 259 lbs., with 16 inches, my name is Turner Brown. The dwarf looks relieved and starts laughing. For a minute there, I thought you said, ‘Turn Around.’”
