General Tso is a fictional Mongolian-American general in the US army. General Tso was first mentioned in You're Cut Off during the protest campaign challenge. The general is based on the brand of Chinese chicken and beef, leading Joe to slip some food puns in his protest.
Joseph "Joe" Gatto had to get strangers to join in on a protest made for him by the other guys. His protest was Impeach General Tso. He complained about how this fictional general makes poor decisions and abuses his power. He couldn't get someone to help him protest because the guy had no idea what Joe was talking about.
