One day this mechanic was working late under a car and some brake fluid dripped into his mouth. Wow! That stuff isn't too bad tasting, he thought. Next day he told his buddy about tasting the brake fluid. "Not bad," he said. "Think I'll have a little more today." His friend got a little concerned but didn't say anything. Next day he told about drinking a cup full of the brake fluid. Great stuff! Think I'll have some more today. And so he did. A few days later he was up to a bottle a day, and told his friend that brake fluid is really great stuff. His friend was now really worried. "You know that brake fluid is poison and really bad for you. You better stop drinking that." "Hey, no problem," he said, ... "I can stop any time."
