There's a growing trend towards PhotoCakes -- birthday cakes whose icing features images, sometimes copies of old baby pictures, cunningly rendered in the many-hued icing now available.
Often these are the sheet-cakes favored for office birthday gatherings for co-workers. And they sit there by the mailboxes all day as people wander by sneaking small slices throughout the day.
I've noticed that people tend to avoid cutting into the photo section as long as possible. As a people, we must have some deeply ingrained reluctance to cut into a baby's face with a kitchen knife. I think this is a good thing, by the way.
I find I have this slightly disreputable desire to arm myself with a small tube of cake-decorating icing that I might whip out when no one is looking and draw cartoon mustaches on those pictures.
I must have some anti-social tendencies. Anti-cake, anyway.
