A real groaner - and no, I'm not sorry. A man went to his dentist because he felt something wrong in his mouth. The dentist looked inside 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 Hollandaise sauce on it. I loved it so much I now put it on everything - meat, toast, fish, vegetables, everything." "Well," said the dentist, "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 plate, and this time use chrome." "Why chrome?" asked the patient. "It's simple," replied the dentist. "Dental researchers have concluded that there's no plate like chrome for the Hollandaise."
