An Ohio teen was sentenced to jail time after he admitted to serving a teacher a semen-tainted crepe as part of a sick joke during a cooking competition at his middle school, a report said this week.

The 15-year-old admitted to bringing in a bag of his semen and dumping it on the french dessert before serving it to his teacher at Olentangy Hyatts Middle School in May, local news station KUTV reported.

He was sentenced to 30 days in a detention center and ordered to complete community service, according to the report.

Seven other students — who were not publicly identified — are also accused of assault and other crimes for their roles in the disgusting prank.

One other student facing charges allegedly soaked barbecue sauce with his urine and served it to four unsuspecting teachers, according to CBS affiliate WBNS.

The sickening joke played out while the teachers were judging a cooking class as part of the “Global Gourmet” course at the school.

Video obtained by WBNS shows one of the students dump a liquid from a plastic bag onto a crepe before presenting it to the panel of teachers.

The video then shows a teacher eating it and quizzing the student about its ingredients.

“Is this made with goat milk or cow’s milk?” the teacher asks the student, according to the video

“Uhh, cow’s milk,” the teen responds.

“Is it fresh-squeezed cow’s milk?” another teacher asks, before another teacher interrupts to say: “I’m not even gonna lie, it tastes really good.”
