Can't tell if serious. Seasons 1,2,5 are the only worth watching. Live season was pretty good too if memory serves me right.
S5 is the GOAT tho imo - Diaz and Gamburyan going ape shit in the house and trying to fight rob Emerson after he called them bitches, the actual fight at the house between Marlon sims (who claimed to have hundreds of street fights) and Noah Thomas, gabe rudieger weight cut, WAYNE WEEMS!!!, The monster lobsta, ANDY "TAKE HIM DOWN" WANG and getting kicked off BJ's team . Not to mention Joe Lauzon, Matt Wiman, gray Maynard and Cole miller were also on the show putting on amazing fights.
Cliffs alone for that season could be it's own thread.
