Do you remember when these famous athletes ran the American Ninja Warrior course?

Over the years, we’ve seen some big names try the American Ninja Warrior course. Besides the world-class athletes that have become our favorite Ninjas, we’ve seen Olympic athletes, NFL players, famous TV stars, and Indy car racers.

Here are a five fun ones to jog your memory. How many do you remember?

Generally speaking, NFL players don’t usually do very well on the ANW course—except for Kamerion Wimbley back in 2012.

Olympic gymnast Nastia Liukin (who is just 5’3” and 100 pounds!) ran the course Red Nose Day.

Harlem Globetrotters star Bull Bullard hit the buzzer in season 4.

We also saw Akbar Gbajabiamila—finally!—take to the course for charity.

Bonus: Usher (sure it was on The Ellen Show and he’s a singer, not an athlete, but our two favorite announcers were there with the play-by-play!)

Who would you love to see tackle the ANW course next season?
