5 of the craziest pranks in the history of The Ultimate Fighter (TUF)

#4. The Upper Decker (TUF 6)

The infamous Jon 'War Machine' Koppenhaver was involved in a truly crazy prank during TUF 6

One of the most disgusting pranks in TUF history took place on the show’s sixth season, way back in 2007. The season, which featured coaches Matt Hughes and Matt Serra, was already a heated one thanks to some incendiary personalities.

Nobody could’ve expected such a crude prank from Team Serra’s ‘War Machine’ Jon Koppenhaver, though – nor could they have foreseen the wild aftermath that followed.

Essentially, Koppenhaver decided to leave an ‘upper decker’ in Team Hughes’ toilet. For those unaware, the prank involves removing the cistern lid from a toilet and then defecating into the tank – meaning feces will flow down once the toilet is flushed.

The prank was puerile and disgusting, but admittedly, it was also quite funny. Team Hughes, however, didn’t see the funny side.

And when Jared Rollins found out what’d happened, he subsequently shattered the cistern lid against a wall before confronting Koppenhaver, leading to a brief pull-apart brawl.

In the end, Koppenhaver and his teammates cleaned up the mess, ensuring that cooler heads would prevail. However, more than a decade on, this remains one of the craziest and most memorable pranks we’ve ever seen on TUF.

#3. The Mariachi band (TUF 14)

Michael Bisping treated Jason 'Mayhem' Miller to a truly crazy prank during TUF 14

2011’s TUF 14 was arguably the wildest season of them all. Featuring a cast of bantamweights and featherweights coached by bitter rivals Michael Bisping and Jason ‘Mayhem’ Miller, it seemed like an explosive moment would occur on every episode.

However, the craziest prank of the season was neither aggressive nor puerile. Instead, it was simply outrageous and downright bizarre. Quite how Bisping and his team came up with such a plan remains a mystery.

The early part of the prank was nothing out of the ordinary. Essentially, Bisping and his assistant coach Tiki Ghosn decided to barricade Team Mayhem into their locker room before unleashing fire extinguishers on them and filling the room with fumes.

This part of the prank would be revisited on TUF Brazil 2 and didn’t go down so well, as a handful of fighters suffered serious breathing problems.

However, this one was a little different due to the random addition of a live mariachi band, which appeared walking through the thick smog playing traditional music as Mayhem and his team desperately tried to escape.

It was our team. Best prank though was the fire extinguishers through the walls followed by a mariachi band. https://t.co/9LBttQwlH3

The prank was downright hilarious and bizarre in equal measure, and even Mayhem, who had gotten into multiple angry confrontations with Bisping over the season, had to acknowledge it as one of TUF’s best. In a bad-tempered season, this was an excellent piece of hijink.
