This is a strange one: a 30-year-old woman named Barbora Skrlova passed herself as a 13-year-old boy ... and even enrolled herself in school!
Barbora Skrlova fled to Norway from the Czech Republic and posed as a 13-year-old boy for four months to avoid giving testimony in a 2007 child abuse case, Czech police said.
She was deported back to the Czech Republic and detained after months of fooling teachers in Norway by passing herself off as a boy named Adam. She was enrolled at a school near Oslo in September by a woman who introduced the 33-year-old as her son.
Skrlova was eventually arrested after the police received a tip-off.

I too thought Nosferatu.
And I'm wondering how she did socially on the campus..
