A dentist found something wrong with one of his patients. The upper plate that had been put in earlier was corroding.
"What have you been eating? " the dentists asked the man.
"All I can think of is that about three months ago my wife 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 contains lemon juice, which is highly corrosive. I'll make you a new plate, and this time use chrome."
"Why chrome?"
"It's simple. Everyone knows there's no plate like chrome for the Hollandaise."
