An Australian couple found themselves upstaged during their own wedding by their 3-year-old son, who interrupted the ceremony to announce: “I have to poo.” Hannah Lienert posted a video to YouTubeshowing what happened at her wedding to longtime beau Ben Lienert.

The woman performing the ceremony is offering thoughts on “the real values in life” to the couple when she is interrupted by the pair’s 3-year-old son, Hudson. “I have to poo!” Hudson announces, causing the happy couple and their guests to erupt into laughter.

A helpful wedding guest swoops in to lead Hudson indoors, where he presumably delivered on his promise.

“That is the definition of being upstaged,” the officiant says, before continuing with the ceremony. “Children and weddings don’t always mix, but they sure know how to make them memorable,” Hannah Lienert wrote in the video’s description.
