Hey-I actually saw this once. The bride burned a nice hole in her veil blowing out the candle. Unfortunately only those in the first rows and the priest actually heard her emphatically say “Sh*t!” but it was pretty clear she said something like that.
One friends wedding we attended. It was Catholic. I’m an escapee and able to phase out the entire ordeal.
But my husbands friends who were sitting in front of us couldn’t it.
When it came time to Bless The Couple (or whatever it’s called) and the congregation raised their one hand to bless the couple, one friend said, in a rather loud voice,
“Heil Hitler”
My laughter was the loudest of the two pews of giggling idiots and could easily be heard on the wedding video.
