A man went to his dentist because he felt something wrong in his mouth. The dentist examined him and said "That new upper plate I put in for you six months ago is eroding. What have you been eating?"
The man replied, "All I can think of is that about four months ago, my wife made some asparagus and put some stuff on it that was delicious... hollandaise sauce! I love it so much now that I put it on everything -- meat, toast, fish, vegetables, everything!"
The dentist said, "Well, that's probably the problem. Hollandaise sauce is made with lots of lemon juice, which is highly corrosive. It's eaten away your upper plate. I'll make you a new one, and this time, I'll use chrome."
"Why chrome?" asked the patient.
"It's simple," said the dentist. "Everyone knows that there's no plate like chrome for the hollandaise."
