The FBI has recruited three girls to teach agents how to pose as teenagers on the internet. [...] The training is part of the FBI's Operation Innocent Image, which aims to track down paedophiles and child porn peddlers who prey on teenagers on the internet, according to the San Fransisco Chronicle. Best friends, Karen, Mary and Kristin were recruited after one of their fathers - an agent involved in the paedophile investigations - watched her instant messaging a friend and couldn't understand what she was typing.

I feel sorry for the agents, who clearly have little idea what's hit them:

The first time the girls gave a quiz, all the agents that took part failed.
One agent insisted that he was right when he answered on a quiz that Justin Timberlake was more popular than Destiny's Child.
Another was upset when the girls told the class that Led Zeppelin just wasn't cool. Appraising the agents' performance, Mary said: "They, like, don't know anything."
