I found this posted in another forum, and had to share.
Funny story, at one point during the wedding rehearsal, the coordinator placed two ushers on each side of the door and said. "You two stand here, like your flanking the people that walk through." I immediately looked at my buddies and said " that gives them +2 Combat advantage, but I'm willing to take the attack of opportunity to walk by in order to get hitched"
Also, Charisma checks were passed, not to mention an numerous Athletics checks on the honeymoon.
