Would you eat a handful of living spiders for $50,000? Or what about a fresh platter of boiled buffalo testicles?

Just the thought of it might make you want to throw up, but believe it or not, Fear Factor contestants have done even more gross challenges that took the meaning of “crazy” to a whole new level.

The series, which first debuted in 2001, made for groundbreaking reality TV. Contestants had to complete a series of mental and physical challenges that involved extreme action stunts, pain endurance tests, and disgusting meals. But while it often left us gagging or chewing our fingernails, it was just impossible to not get hooked on all the suspense! And of course, it was always entertaining to see famous faces get involved — including John Travolta and George Clooney's ex, Sarah Larson.

After airing for six seasons on NBC, the show got canceled, but due to its popularity, it returned in 2011. The revival, however, only lasted for one season. And now, five years after its final episode, MTV has called for an official reboot with Ludacris as its host.

The show will have eight participants paired up into teams, and as usual, they’ll be battling it out for a final cash prize. It's also set to premiere on May 30, which is right around the corner. So in honor of its return, we’re taking a little walk down memory lane to relive the show’s craziest and most disturbing challenges ever.

Note: A few of the images are quite graphic, so if you’re queasy or you happen to be eating, you might want to keep a bucket nearby…
