An old man was sitting on a bench at the mall. A young man walked up to the bench and sat down. He had spiked hair in all different colors: green, red, orange, blue and yellow. The old man just stared. Over time, the young man noticed the old man was staring at him. The young man finally said sarcastically, "What's the matter, old man, never done anything wild in your life?" Without batting an eye, the old man replied, "Got drunk once when I was in the Marines, on a tropical island, and had sex with a parrot. I was just wondering if you were my son."
