I just have a few things to say...
Where In The World Is Carmen Sandiego?
Teenage Mutant Ninja Turtles, cartoons, video games, action figures, comic books, children's books... They're all great. I still have a lot of the action figures.
Every once in a while, I get real nostalgic and play TMNT4: Turtles In Time under zsnes (I lost the SNES cart

)
Z-Bots. Pogs. Transformers. X-Men. Batman: The Animated Series. Saved By The Bell. Doom. My old 12MB Voodoo2 (I'm going to encase it in lucite, eventually). Dial-up internet access (Netcom owned). The time when MTV didn't suck as much as it does now (the first music video I ever saw was Green Day - Basketcase, followed by Soundgarden - Black Hole Sun). Sonic The Hedgehog, Super Mario Brothers (video games, tv shows, etc). Sega Genesis, SNES, Virtual Boy (Yeah, I had one of those

), Gameboy. My K6-2 300MHz (3DNow! + Voodoo2 + Quake2 = pure beauty). And last, but definetly not least, one of the most sentimentally meaningful things ever in my life, Kiri Te Kanawa's rendition of Blue Skies.
