A dentist found something wrong with one of his patients. The upper plate thathad been put in earlier was corroding. "What have you been eating?" thedentists asked the man."All I can think of is that about three months ago mywife made some asparagus and put Hollandaise sauce on it. I loved it so much,I put it on everything now.""That's the problem," the dentist said, frowning. "Hollandaise sauce containslemon juice, which is highly corrosive. I'll make you a new plate, and thistime use chrome.""Why chrome?""It's simple. Everyone knows there's no plate like chrome for theHollandaise."
