Back when I was stationed in DC (and swore never to go back) one of the radio personalities caused a minor uproar when he started off his show by saying he had brought in a handgun and laid it on the table in the studio. (It never occured to anyone to question that he actually had one.)
He said he was doing this to make a point, that a handgun was totally incapable of harming anyone, and to prove the point he would leave the gun on the table until either the show ended in 2 hours or the gun shot someone.
As you can imagine, before the 2 hour show was over he had the libs in a tizzy with threats to his safety and calls to the cops. His gag was a thing of beauty.
