I stick GUNS behind my ear, for later chewing. Yes, I chew guns. AK-47s are my favorite. Anyway, back on topic.
Basically all my systems are in good condition. I bought my GameCube used and spent hours cleaning it (it wasn't even all that dirty) until it was glowing. Sadly, my old, black-and-white Game Boy has a smashed screen, and my old Game Gear simply crapped out one day and stopped working. My slimline PS2 is still in excellent condition, although the USB ports are a tad dusty from underuse (I don't play SOCOM nearly as much as I used to). My N64 is currently in my sister's possession and is in great condition, though I can't say the same for the dust-coated cartridges. In my garage is an old, old Sears Pong system that has a noticably torn and musty box, although I haven't seen the system itself. And my SNES is in terrible condition, with cracks, faded, warped plastic, bullet holes and deep scratches made by an axe.
