Four good old boys were just sittin' around trying to decide what the fastest thing was. The first guy said "I think it's a thought, It happens before you realize it". They all said yea, that's fast alright. The second guy said, "I think it's the blink of an eye". It's over before you know it. They all agreed. The next one said," It's got to be light. Heck, when you turn on the light switch it's there and turn it off it's gone. It's instant. They all said no doubt that's fast. The last guy said " I think it's diarrhea. They all looked at him funny. "Why in the world would you say that"?. Well, he said, when I got up this morning, before I could think, blink or turn the light on I $hit myself.
