Back in the 80s, the music industry came up with its dumbest campaign up to that point: the campaign to convince their customers that taping vinyl, making mix tapes, sharing taped albums with friends, all of that, was a form of theft and would destroy music itself.
They put these "home taping is killing music" graphics on everything from stickers to the sleeves of LPs you bought in the shops. Home taping didn't kill nothin' (turned out to be no more deadly than P2P!).
The media geniuses at Downhill Battle have produced a great tee that recycles the HOME TAPING IS KILLING MUSIC slogan and gilds the lily with this tagline: AND IT'S FUN. I laughed till it hurt.
