Lisa: In case you were wondering...

Despite being married to a high school football-playing jock, I have no interest in football--I didn't in high school, and I don't now. And forget watching football on TV; on Superbowl Sunday, I only watch the halftime show. That said, I have fallen in love with Friday Night Lights.

As a relative newcomer to high school football culture (and certainly to the all-encompassing version that surrounds Texas high school football), I suddenly found myself needing to know the difference between a cheerleader and a rally girl--and whichLyla Garrity is.

Exhibit A: In FNL's first episode, Lyla says she has to go to "rally rehearsal," so I figured she was a rally girl.
Exhibit B: At the end of episode 2, the Dillon rally girls are shown delivering baked goods to their Panthers in a sequence that ends with Lyla bringing Jason a cookie in the hospital. Is this because she's his rally girl, or does she do it (and does he forego the services of a rally girl) because she's his girlfriend? Incidentally, (just like Wallace's spirit boxes on Veronica Mars) treat-bearing rally girls apparently do exist in real life.
Exhibit C: The show definitely considers cheerleaders and rally girls to be two separate things. Lyla notes their uncharacteristic alliance (and by implication, their accustomed rivalry) in making Jason's banner. The casting calls for extras support this, noting that 'cheerleader' is a specialty role, while rally girls (though required to be "super cute") receive standard pay.
Exhibit D: The Wikipedia entry on cheerleading doesn't mention rally girls at all, but I love that the neutrality of the article is in dispute.
Exhibit E: TWoP forum participants know all. BananasFoster explains that being a cheerleader is more prestigious and exclusive, while anyone can be a rally girl. TexasTumbleweed agrees, adding that the rally girls are indeed the providers of spirit boxes and banners. It sounds like rally girls are a lot like what we called "pep club" at my school.

Verdict 1: I think Lyla must be a cheerleader. She's often shown on the sidelines of the game, cheering in the uniform and with pom-poms, just like my school's cheerleaders. Plus, she was dating the star quarterback--clearly a role only a cheerleader can fill. "Rally rehearsal" must have meant practicing for a rally, not practicing with her fellow rally girls.
Verdict 2: I have spent too much time thinking about this.
Verdict 3: I love the internet.
