Farcus is a fictional character in the Hey Arnold! TV Series.
He is the P.S. 118 school janitor. He apparently is on good terms with Principal Wartz, and seems rather impatient with the students. He was seen throwing Eugene's ruined bike into the dumpster completely unsympathetic to Eugene's despair.
He once caught a student named Mike Smedvick playing hookey a few years ago.
