What was meant to be a funny dare turned into an utter embarrassment for an American exchange student, who found himself trapped in a giant stone vagina in Germany.
Firefighters had to be called in to deliver the man, head-first, to safety after his feet became trapped in the large marble sculpture at Tubingen University in Germany.
The unnamed man is believed to have been dared to climb inside the sculpture, which sits outside the university's institute for microbiology and virology.
But his legs soon became wedged in the carving and, despite labouring to free himself, the experts had to be summoned.
A local newspaper, Schwäbisches Tagblatt, reported that the emergency services received a call at 1.45pm on Friday to say a young man was "stuck in a stone vulva".
A total of 22 firefighters, five fire engines and a number of paramedics were sent to the scene, and quickly freed the man "by hand without use of equipment", the newspaper reported.
Erick Guzman took photographs of the incident and posted them on Imgur, saying: ‘I was there!!! He just wanted to take a funny picture.
"The fire department was not really amused, and he was really embarrassed."
The sculpture, by Peruvian artist Fernando de la Jara, has sat outside the university for 13 years and was not damaged.
The man was not harmed, although his reputation has been.
