Lo was a cheerleader in high school, which she's not particularly proud of--though it does go to show that you can't spot an ex-cheerleader just by looking at her. (Em, meanwhile, doesn't even have the coordination necessary for step aerobics, and was therefore relegated to the marching band in high school.)

It turns out that sometimes, former cheerleaders grow up to be banner-waving feminists-slash-sex writers. And sometimes, they grow up to be lawyers for the National Organization for Women-slash-Supreme Court judges. Yes, we're looking at you, Ruth Bader Ginsberg (we shit you not).

Let's play Cheerleader/Not a Cheerleader! After the jump, find out which of the following celebrities pom-pommed their way through high school or college. (Thanks to WMUR's "They Started as Cheerleaders" slideshow for the answers. Via boingboing.)

1. Madonna
2. Paula Abdul
3. Lindsay Lohan
4. Michael Douglas
5. Jessica Simpson (Okay, so this one's a gimme)
6. Samuel L. Jackson
7. George W. Bush
8. Halle Berry
9. Dwight D. Eisenhower
10. Aaron Spelling
11. Mandy Moore
12. Cameron Diaz
13. Katie Couric (Another gimme, duh)
14. Meryl Streep
15. Jamie Lee Curtis

Okay, so that was a trick question--they were all cheerleaders. Every single one of them. Yep, even Dubya, who was a cheerleader at both his prep school and at Yale. Somehow, this explains a lot.
