You should make a card that reads "I Don't Get These Things". It would be right up there with the Myspace image that reads "No Hipster Image Available". Hiliarity would ensue!

I seriously don't get them. They're right up there with stupid scooter rally patches for mods & studs/pins on leather jackets for punks. How many ya got?!

"I'm also addicted to boobies" would also be a good one. But let's stay on task!
