Here's one my mom sent me-

An old man was sitting on a bench at the mall. A teenager 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. Every time the teenager looked, the old man was staring. The teenager finally said sarcastically, "What's the matter old timer, never done anything wild in your life?

Without batting an eye, the old man replied, "Got drunk once and had sex with a peacock. I was just wondering if you were my son."
