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 - . 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.
