Toot was an illegal blood sport operated by the Ganymedian mafia.

Red Dwarf flight coordinator George McIntyre, who had a gambling problem, would often partake in toot when the mining ship stopped off around the solar system. McIntyre ended with massive debts to the Ganymedian mafia because of this, Taking out a loan on Mimas to pay the mob back, the loan company turned put to be a mob front and McIntyre was asked to meet with their representatives to arrange payment. When he couldn't pay up, three bodybuilders force fed him his own nose.

Later that evening, George shot himself aboard Red Dwarf. Since he was the highest ranked dead crewmember, he replaced Frank Saunders as ship's hologram. As a dead man, he could no longer be targeted by the mafia. (Infinity Welcomes Careful Drivers)
