A Little Walk With Dad.

So I was walking down the street with my dad the other day, and two youngsters, possbile who did not even hit the 15 yet, walked infront of us. And they were talking loudly and one asked the other "Why do some old dudes walk like they´ve shit them self?"

My dad promptly answered "97% its lower back pain, 3% is a misjudged fart."
