Aside from the obvious inappropreateness of a four year old having a cake themed from one of the most violent games ever is the question of whether or not a four year old is even capable of playing the game. When I was four the most violence I ever encountered was on Knight Rider. I don't think the Atari console was even out yet. Yikes.
This post is dedicated in loving memory to my husband whom I will never see again due to today's release of GTA4.
