An American exchange student got stuck inside a stone sculpture of a vagina last week in Germany.

It took more than 20 emergency responders Friday to free the young man, according to reports in the German newspaper Süddeutsche and The Guardian. He had wedged himself inside Pi Chacan, a 2001 stone sculpture by Peruvian artist Fernando de la Jara, in front of Tübingen University’s Institute for Microbiology and Virology. The police in Tübingen first learned of the incident when they received a call reporting that “a person is stuck in a stone vulva.”

The city’s mayor Boris Palmer said he could not understand how the student got himself in that situation in the first place, “even taking into account adolescent fantasy,” Süddeutsche reports.

No word on whether the student was trying to take a selfie.
