It was awesome to find your own name (Impaled Gail was as close as you were gonna get to my spelling). If you had a common name, like Brian's, you might get a choice of cards (Booger Brian, Fryin' Brian, Brainy Brian.) Better than that was if you had an enemy, and you found THEIR card, especially if it was a really negative one (Nasty Nancy!).
I was a little old for GPKs when they came out, but I always loved Wacky Packs and Mad Magazine, and really, this was just another jaunt down that road of goofy gross-out parodies. Topps is now releasing Flashback sets, so you can trip down memory lane with such cards as Rappin' Ron (a Ron Reagan lookalike) and Have a Nice Dave (yellow smiley face dude).
