A man went to his dentist, complaining that his denture plate was corroding away. The dentist examined it and asked the man, "Have you added anything new to your diet?" The man thought for a second and said, "Well, the only thing I can think of is that my wife has been making me a lot of eggs benedict lately. I never tried it before recently and I really love the dish. She makes it for me now at least a couple mornings a week."
"Hmm," the dentist says. "Do you use a lot of hollandaise sauce on your eggs benedict?"
"Oh, yes, I love the hollandaise sauce. I always get a big ladle-full on top," the man replied.
"Ah!" the dentist says. "There's your problem. Hollandaise has lemon juice in it, so it's corrosive. I am going to fit you for a new plate made of chrome."
"Chrome! That's odd. Have you fitted anyone for a chrome plate before?"
"Yes, it won't corrode like your old one," the dentist replied. "In fact, this is so common there is even a saying about it."
"A saying?" the man asks him. "I've never heard it."
"You've never heard? Everyone knows there's no plate like chrome for the hollandaise!"
