The episode "Comedians", before being heavily edited, was held responsible for the deaths of two children when, while left unattended, they located matches and set their trailer on fire. After the incident, many episodes were edited to remove fire references ("Comedians", "Tornado", "Stuart's House") and such references stopped appearing (including Beavis' signature "fire fire FIRE!" chant).
This episode has been released exclusively on the "Still stupid" PAL VHS tape. It is heavily edited though with all fire references from acts I and IV removed.
