I didn't like the sandwich one, if you look at the baby it is crying and looks pretty distressed. The microwave one is stupid - I feel sorry for the poor baby all squished in and she doesn't look too happy either. The most shocking one for me is the baby with a great big heavy snake lying on top of it and over it's face, poor thing. Oh and the lion one is awful too.
Loads of the others are quite funny - the karate one, the duct tape one made me smile, and the playboy one (I agree with the poster who said the baby is thinking "look at the lunch on that"). Basically it's the ones where the babies look terrified that upset me. I have taken plenty of my own funny pics of my 1 yo DS but I wouldn't be getting my camera out if he was upset, scared or crying. That's just not on and I don't care if it makes me a party pooper.
