Boy Ruins Mum's Perfect Proposal By Pulling Pants Down & Doing Something Cheeky Right Next To Her

Everyone wants the perfect marriage proposal. If you're planning one, no doubt you'll have mapped out every tiny detail in your head and if you're hoping for one, you'll have something romantic in mind.

Lots of people try to prepare for every eventuality and all the little details that might not go totally to plan. But there's no way you can be prepared for a situation like this.

Kevin Przytula decided that it was time to pop the question to his partner, Allyssa Anter, in Bay City, Michigan. They got someone to film the special moment so they can treasure it forever.

What they probably didn't anticipate was Allyssa's three-year-old son Owen deciding to steal their thunder by dropping his trousers and peeing beside them.

As 33-year-old Kevin was down on one knee waiting for his partner to say yes, Owen clambered past them, pulled his trousers down and started to wee.

As the person filming the romantic proposal starts laughing and alerts them to the hilarious mishap, Kevin turns around and exclaims: "Oh my God, he's peeing, are you serious?"

Alyssa was able to shed some light on her son's actions: "He pees outside at home, sometimes in the yard and we went and got ice cream the other day and he did it in the parking lot there."

"He just does it without telling anybody; he just pulls his pants down and goes."

Allyssa said that he "stole the show" and that although they had been potty training the Owen for a month, more training might be needed.
