Trying to stop a wedding
When the guy gives that wedding-stopping speech in a movie, do you really think the bride hadn’t already thought about all of the issues he brings up? Of course, she has! And she decided to walk down the aisle anyways, even though her groom isn’t as adventurous and or good-humored as she wants him to be. The wedding-stopper would be escorted out by security, if not punched out by the groom’s friends.
