I'm finding myself agreeing with some unlikely people these days. There was nothing funny about the "joke" and all of those "practical" jokes are only funny if you think it's OK to humiliate and demean someone. To call enjoying that having a "sense of humour" is like calling bear-baiting or cockfighting a "sport". I'd still string the DJs up. The male one by his balls and the other by the most painful equivalent.
