I was explaining this phrase to my non-UK colleague and how it's usually accompanied by an awkward titter around the church/registry office etc. He asked if I'd ever been at a wedding where someone had spoken up & what happens next. I haven't and I have never heard of it happening... So my question to MN - has anyone ever been at a wedding where there's been a response to the question on any reason why the couple can't marry?? What happened next?
