“Does comedy on television cause comedy in the streets?”

One argument about television is that it features too much sex and violence, and that this causes those problems on the streets. Television talk show host Dick Cavett was asked about violence on television, and he answered in October 1977:
 
“I don’t know if violence on tv causes violence in the streets. Comedy on tv has not resulted in comedy on the streets.”
 
Cavett’s quip has been a much-cited statement on the topic, even if not everyone believes the logical argument.
