Parents' annoyance level: 3/10. They were expensive dolls and you, of course, had to have all five to avoid breaking up the band.

Spice Girls and girl power itself ruled the '90s. You, or your sister, had all the cassettes, quoted the movie daily, and collected all five of the girls in doll-form. Then, you weren't allowed to take them out of the box and play with them because your mom thought they'd be worth something someday. You did it anyway, and that's why you had to take so many loans out for college.
