A father is now facing jail time for letting off a stink bomb in his son’s school after his son was suspended for doing the same thing.

Jason Festerman, of Marine City, Michigan, was called to the school after his son was suspended for spraying the stink bomb spray, called “Liquid Ass,” in his classroom at Marine City Middle School.

Festerman said he was innocently checking whether the pump spray worked, and it did, discharging the foul-smelling odor in one of the school’s offices.

School officials say it didn’t exactly go the way Festerman said, however, as they recall he “attacked teachers and administrators” with the stink bomb spray.

According to a description of the “Liquid Ass” product on the company’s website, it emits a scent that resembles “butt-crack smell with hints of dead animal.” Lovely.

Festerman was charged with disorderly conduct, which carries a possible penalty of $200 and/or 90 days in jail. 

Staff at the school believe he was taking revenge over his son’s one-day suspension. 

“We’ve gone to Kmart. We’ve had our kids with it. We’ve done it at like Dollar General. Everyone laughed,’ said Festerman, defending his family’s use of the odorous prank.

He did say, however, that he and his partner Rekiba had punished their son for bringing their property to his class and disturbing the room.

Mr. Festerman also denied deliberately setting off the spray.

“I wasn’t spraying it to spray it.  I was checking, unfortunately I had to pump it, to see if anything was in it and it was,” he explained.

A likely story, Mr. Festerman.
