I’ve always felt sorry for joke thieves. I’ve never once gotten angry about it. I always remember the scene from Powell’s The Red Shoes. Lermontov, the impresario, counsels the young composer, Craster, whose just had his score stolen by an older, burned-out composer: “It is worth remembering, that it is much more disheartening to have to steal than to be stolen from, hmmm?”
Patton Oswalt responds to some hack named Nick Madson stealing his and Louis CK’s bits, then telling other comedians who called him on it that HE really wrote those bits, so he wasn’t stealing. Congratulations to Mr. Madson – you’ll carry ’La marque de la Douche’ for the rest of your life.
