What happens if someone says "I object" in the middle of a wedding?

That question originally was asked to make sure that one or the other of the people getting married was not able to legally be married, like if they were already married without being divorced. The purpose is not for any bozo who happens to not like the idea of them getting married to express that opinion. That would not be considered a reason that the couple could not be married. And I agree with one of the others, that person would make himself look like a complete idiot.
