I too enjoy dark humour but the second I saw the baby with the gun my insides just started squirming and I felt so uncomfortable. I understand the point you were making but I don't quite get how filming a baby with a gun represents your anxiety over being responsible for his life.
I'm sure you're a good guy and no doubt you took at least some of the bullets out of the gun (see, I like dark humour!) but there are just too many tragedies that occur with children whose parent's don't secure their firearms properly for me to find this amusing.
(This probably makes me a terrible hypocrite, but I loved the baby in the bath one)
