Great joke

Got an email from friend with this funny joke, just wanna share it out...

An old man was sitting on a bench at the mall.
A teenager sat down next to him. He had spiked hair that was red, orange, yellow, green, blue & violet. The old man stared. Whenever the teen looked, the old man was staring.

Finally, the teenager said sarcastically: "What's the matter, old boy, never done anything wild in your life?"

Without missing a beat the old man replied: "Got drunk once and had sex with a peacock. Just wondering if you were my son."

muahahaha!!!!
a GOOD ONE
