“I’m scared to death.”

It’s not every day you hear Mike Tyson of all people utter those words, but that is exactly what the former heavyweight boxing champion said during yesterday’s appearance on Discovery Channel’s Tyson vs. Jaws: Rumble on the Reef.

The show, which was part of the network’s annual Shark Week, “pitted” Tyson against sharks in a three-round format.

UFC President Dana White and famed announcer Michael Buffer helped set the stage, and it did not go unnoticed that Tyson—who famously bit Evander Holyfield’s ear in a boxing match—said “someone’s going to get bit” in a promotional video.
