Space Princess as a valid career goal, pants, and other important things.
As popular as nostalgia is right now (and who hasn't freaked out because they saw a t-shirt with '90's X-men cartoon Gambit on it and spent nearly thirty bucks on it? Right?) we obviously don't have access to a time machine to go back and badger our past selves into keeping everything. So... unless you have access to an actual bunker and were able to keep all of the things, you're probably something like me, and have kept a few important pieces that remind you of how cool, baby you was.
