Okay, now this is creepy. A 29-year-old woman has been arrested in New Jersey after enrolling at a local high school and posing as a freshman for four days on campus.

I'm sorry, but why in the world would someone do this?

Students at New Brunswick High School are upset after learning at a school board meeting Tuesday night that a 29-year-old woman was arrested for using a fake birth certificate to enroll and attending school for four days.

Police have charged that woman, Hyejeong Shin, with one count of providing a false government document with the intent to verify one's identity or age. The school circulated a letter with her picture.

Here's what the woman looks like:

She looks young, but not freshman young.

Maybe next time say you're a junior…?

Anyhow, students and parents were understandably irate when they found out about this. According to students, not only did they see Shin in the classroom and in the halls, but some of them were contacted by her and asked if they wanted to hang out with the woman.

"Some of the girls I know, the girl did ask them to hang out at Commercial Avenue, but they never showed up, and she started acting weird with them," one student said. "It's scary because you never know what could happen."

Luckily, this only lasted four days and now Shin has been arrested.

Nice try, lady.

Maybe next time.

As police continue their investigation, the school superintendent says the district will re-examine the enrollment process to better identify false documentation.

Yeah, ya think?!
