Hmmm...Scrabble on their honeymoon....actually I can picture it!

It gives Hermione a chance to gloat about how smart she is without really gloating.
I like how they were arguing about who had it worse(guys when they wear tuxes or girls when they wear dresses)
I think it would have been funny for them to be still arguing about that before they entered the reception hall and Sirius overhearing them.
Now Sirius,being the proud Marauder he is,probably would have cast a spell a spell to transfigure their clothes so that Harry would be wearing the dress and Hermione would be wearing the tux,so they would be wearing eachother's outfits when they walked into the reception.
I suppose that would make tossing the garter belt and the boquet(That's it I'm finding my dictionary,curse my knowledge of words but horrible spelling)toss kinda awkward.
