OHHH come on ! You can't tell me you didn't do some hilariously stupid crap when you were 4! Kid just learned a valuable lesson and you write him off as a lost cause!!!
Oh, I did some really stupid crap at that age, but I don't think it extended to that level of stupid! And, if my Momma had been standing there (which his obviously was), she never would have let me be that stupid! I might have been hurting afterwards, but it would have been my arse, not my crotch!
