Dad's reply

I took my dad to the mall the other day to buy some new shoes (he is 66).  We decided to grab a bite at the food court.  I noticed he was watching a teenager sitting next to him.  The teenager had spiked hair in all different colors - green, red, orange, and blue.  My dad kept staring at her.  The teenager kept looking and would find my dad staring every time.  When the teenager had had enough, she sarcastically asked: "What's the matter old man, never done anything wild in your life?"  Knowing my Dad, I quickly swallowed my food so that I would not choke on his response; I knew he would have a good one!  In classic style he responded without batting an eyelid ....  "Got stoned once and had sex with a parrot. I was just wondering if you might be my kid."
