I attended a wedding as a guest of a family member and when thr pastor said that the doors busted open to the sanctuary and a man appeared and started to say "I do!" but two huge ushers, one who was my date quickly grabbed the guy before he could say anything but "uhhh" under the arms and literally lifted him up off the floor and carried him out. The wedding continued as normal.
Turned out the guy was the ex of the bride. Strangest sight I ever saw.
