A T-Rex takes on the ‘American Ninja Warrior’ obstacle course

Something huge and prehistoric had people screaming (out of sheer delight) in an episode of "American Ninja Warriors."

A T-Rex tore through the obstacle course designed for the show. He did not officially complete all the challenges, but he was permitted to do the final task: Climb a wall and raise his short arms in victory.

Not bad for a 65-million-year-old extinct carnivore from the Cretaceous period!

The man inside the suit, Reko Rivera, was a previous contestant in the show...and he actually did better in costume.

"American Ninja Warrior" is a televised test of endurance similar to Japan's "Sasuke". It is specifically designed to showcase agility, speed, and strength. — AT, GMA News
