Four-Wheel Roller Skating > Cure for AIDS, Cancer, Leukemia, Common Cold, etc. combined
Seriously, I spent every Saturday from the age of seven through ten at the roller rink, skating to "Girlfriend" by Pebbles, eating shitty pizza and playing Gauntlet. I had four birthday parties in a row at three different skating rinks. I say this not because it's something to brag about, but because I feel sorry if your childhood did not resemble mine. Unless your parents owned a roller skating rink, of course.
