Hypnotist?

Visiting the aquarium during feeding time, a hypnotist said to the man feeding the fierce shark, “You know, I could hypnotize that shark.” “You’re crazy! He’ll rip you limb from limb,” the feeder said, laughing. “But, hey, if you’re so brave, be my guest.” The hypnotist jumped in, swam to the shark and stared it in the eye for a full minute. The animal paused, blinked, and then tore into him. The bleeding man slowly made his way out of the tank. “I thought you could hypnotize him,” sneered the feeder. “I did,” the hypnotist said, holding his arm. “Now he thinks he’s an alligator.”
