It's not because he has objections to the wedding
There are things that can not be postponed. At least that was the story of 3-year-old Hudson Leinert, who expresses an urgent need during his parents' emotional wedding speech. Take a look at this funny video on how the wedding party responds to the disruption.
"I have to go to the bathroom" - that's actually something you do not want to hear during an emotional wedding speech. But it's just cute, as little Hudson could not wait and ran to his parents at the wrong moment. His parents and the wedding guests will never forget that!
