6. Ken Shamrock and Tito Ortiz (UFC 40)
Ken Shamrock and Tito Ortiz really did not like each other, though perhaps now they have both reached a stage where they can reminisce about days of old, and bond over what gigantic douchebags they both turned out to be.
In this pre-fight press conference however, Ken Shamrock would cut a pro-wrestling promo on Ortiz with the utmost sincerity, but Tito countered by simply laughing at him. It was probably the funniest thing Tito Ortiz has ever done. Shamrock let him get under his skin clearly, which basically wins it for Ortiz.
Ortiz would later go on to demonstrate that Shamrock had no business being in the cage with him throughout their one-sided trilogy.
