Shia LaBeouf‘s elevator stint has taken a surprising turn.

The eccentric actor, who on Friday spent 24 hours in an elevator at Oxford Union, punched a fan in the face in the middle of the social experiment — at the student’s request.

The Oxford student, who waited in line for hours to get into the elevator with the 29-year-old actor, claimed to be a performance artist himself who wanted a punch from LaBeouf for a project of his own.

“I’m a performance artist. Can you help me with completion of my next piece by punching me in the face?” the student asked.

“Oh man, you want me to punch you in the face?” LaBeouf replied. “I don’t want to punch you very hard!”

The student told LaBeouf not to be a “p—y,” but the actor continued to balk at the request.

“I don’t like doing it though…I just met you.”

The doors of the elevator soon close, though the punch is audible.

LaBeouf’s 24-hour experiment concluded at 9 a.m. Saturday morning.
