It's that time of year again, when nerdy high school kids make national news by asking grown women in sexy professions to the prom.

Austin Moore is a junior at Regis High School in Stayton, Oregon and one of his buddies has a cousin named Mariah Rivera who's a Las Vegas showgirl.

Austin sent Mariah a message on Instagram asking if she'd want to come to Oregon and go to the prom with him. She told him she'd do it if he tweeted about it and got 10,000 retweets.

He posted the tweet a little over a week ago and started racking up the retweets. But when he got to around 1,300, his principal stepped in. He says the school handbook bans anyone over 20 from school dances, so Mariah can't come, regardless of what Twitter thinks.
