Corrected entry: Bender is surprised to know that the Ultimate Robot Fighting League is the most brutal form of fighting in the universe, yet at the beginning of the episode he claims that he loves "The Masked Unit", a well known fighter in the U.R.F.L, so how could he not know something like how dangerous a sport that he loves is?
Corrected entry: Master Ffnog could not have possibly put on that full body suit and connected it up to the TV in the time that elapsed from when he talked to Leela to when the bell rang to start the battle.
Correction: The robot probably has some basic AI of its own, enough certainly to walk into the ring and punch Bender, giving Fnog time to get into the suit and control him for a real show of pummeling and skill.
Correction: Even though he knew it was fairly dangerous, he obviously didn't know it was the MOST dangerous form of fighting in the UNIVERSE.
