The groom and the best man praying right before he walks to the alter. Nothing would melt my heart more than to get my wedding pictures back and see this among them. Maybe a picture of the whole grooms party laying hands on the groom?
Bride & Groom - Cute for Bridal Pictures! Except I'd do bride knocking and groom opening. Or you could do groom trying to shove open the door and bride and bridesmaids on the other side trying to shove on the door to keep him out.
I kind of love the idea of this wedding party collage, though maybe the funny faces aren't necessary? I like how you can actually see the bridal party faces close up and, again, see that these people have personalities.
