If you watched Pryor because he was funny (either because of or in spite of his vulgarity), congratulations: you've just had your behavior influenced by an entertainer.
If you became calloused to vulgarity because of Pryor and repeated his jokes to others or made up jokes after the same model, congratulations; you've just had your behavior influenced by an entertainer.
If you laughed, congratulations, your emotion was influenced by an entertainer... :)
So you're not talking about long-term behavior, just what takes place during the viewing? OK then, I didn't know that was what he meant.
