When I was first married we lived around the corner from a house full of welfare people. There was a mother and a few teenage daughters and each of them had 3 or 4 kids each. There were around 15 or 20 kids running around that place all the time. The house was barely a shell of a house. The doors were falling off and most of the windows were broken and to say the yard was in a state of disrepair would be to put it mildly, an understatement.
I was driving past the house one day and ALL the little boys were bald and ALL the little girls had very short hair. I stopped and hollered at one of the boys, "Hey, why'd y'all all shave your heads?"
The little boy laughed and said, "to get rid of our lice!!!!"
VROOOOM! I was out of there!
