This is just retarded and quite disgusting. Beating the shit out of small children is not something I would usually think about or joke about. It's like joking about molesting children or something. Sick. The youngest person I would ever use physical force against is maybe about 13- 14 or something but only if they were big enough and only if I caught them vandalising our car again. Lil' bastards.
I'd be quite interested to know what kind of person sits there and actually thinks of stuff like this. 5 year olds for christ sake WTF?
