Kevin Przytula planned to propose to his girlfriend, Allyssa, over the weekend in Bay City, Michigan. He brought their 3-year-old son Owen along, as well as a friend to film the moment as he popped the question.

Przytula stopped his girlfriend in front of a fountain and romantically dropped down to one knee. Just as he pulled out the engagement ring, Owen dropped his pants. At the moment his parents became engaged, Owen was answering the call of nature.

Przytula kept his gaze on Allyssa. “I love you with all my heart,” he said, taking her hand and slipping the ring on. Allyssa said “yes” and gave him a kiss. All the while, Owen was letting loose behind his father’s back.

The friend filming the proposal started giggling uncontrollably as Owen peed behind his parents, who were so focused on the engagement they had no idea he was stealing the show.

“Oh my God. You guys?” the friend said through laughs. Finally, Przytula turned around and realized what Owen was up to.
