A Michigan boy found a way to make his mark on the occasion of his mother’s marriage proposal. Allyssa Anter said “yes” Saturday to the question popped by her boyfriend (Kevin Przytula). Video shows the bride-to-be and her man-on-bended-knee are unaware that right next to them, 3-year-old Owen had dropped his pants to urinate. They were alerted to the pint-sized proposal crasher by the giggling videographer, the boyfriend’s 11-year-old daughter. Mom Allyssa says her son “stole the show,” and acknowledges his potty training is a work in progress.
