Penn has a fun little story with this trick...
he was stung over twenty times, and had an allergic reaction but refused to go to a doctor. He had a doctor friend he was chatting with threatened to have the Board of Health shut his show down if he didn’t go to the hospital. The doctor insinuated that Penn was doing heroin and was undergoing an allergic reaction, as doctors do, until Penn reminded him about the bee trick. Then the doctor just kicked him out, saying he was “too stupid to have a doctor” because if he’d just told the doctor about the bee trick it would have been clear this was only an allergic reaction.
