I took my dad to the mall the other day to buy some new shoes (he is 84).

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 colours: green, red, orange and blue.

My dad kept staring at him.

The teenager would look and find him staring every time.
When the teenager had enough he 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 knowing he would have a good one.

And in classic style he did not bat an eye in his response:

'Got stoned once and f*cked a peacock. I was just wondering if you were my son.'
