Having Cake and Eating it Too?

Does anyone else read Dear Abbey? I am a bit confused about this whole shoving a kid's face into a cake thing? I can't believe that this really happens. Is it some sort of cultural or family tradition to shove your kid's face into a birthday cake? I don't know anyone who this has happened too and I've never even heard of anyone discussing it being done? I have read in Dan Savage's book Skipping Towards Gomorrah of the kid who got an erotic kick out of having a cake shoved in his face, but doing it to your kid on their birthday?

What a waste of cake!
