Should the bride and groom smear cake on each other at the wedding reception?

No. They should shoot full cakes at each other from either end of a soccer field, from trebuchets which each built at their pre-wedding parties with the help of friends. The bride & groom stand on platforms, positioned randomly along the ends, and the groomsmen & bridesmaids adjust the trebuchets. The assault ends when one of the two is covered in cake and/or frosting on at least 50% of their fronts.

The winner...well, the stakes are up for negotiation...
