A man goes to his dentist and complains that his upper plate is rotting away. It is crumbling to bits. The dentist asks him if he has had a change in his diet lately. The man replies that yes, he has. His wife has been making a lot of Hollandaise sauce and he loves it. The dentist smiles as he says, well now I know your problem. Hollandaise is corroding your upper plate because it contains a lot of corrosive and acidic things such as lemon juice. "I'll make you a new plate out of chrome". "Why chrome?" the man asks. "Because there's no plate like chrome for the hollandaise. replies the dentist.
