Brake fluid

Did you hear about the mechanic who got a taste for break fluid? He was fixing a car one day when some accidentally go into his mouth. He liked the taste and so started drinking it regularly. When his friends realised what he was doing they were understandably concerned about him. They decided they need to speak to him. “Hey man” they said “this can’t be good for you. But he replied “Don’t worry. I can STOP any time I want.”
