Giants' fan Colin Hanks, son of Tom Hanks, made a documentary about Crazy Crab the Giants' anti-mascot of the 1984 season for ESPN. 1984 was a time when every baseball club was creating their own furry (or feathered) mascot. The Giants decided to troll the those other teams by creating a commercial introducing Crazy Crab. Then they decided to troll their own fans by having Crazy Crab take the field during games. The fans of course hated him and started by throwing food and were soon throwing balloons full of urine at him.
The story ends when two San Diego Padres from the 1984 team body slammed Crazy Crab and injured the performer Wayne Doba's back and sidelined him for the rest of the season.
