This guy goes into his dentist's office, because something is wrong with his mouth. After a brief examination, the dentist exclaims, "Holy Smoke! That plate I installed in your mouth about six months ago has nearly completely corroded! What on earth have you been eating?"
"Well... the only thing I can think of is this... my wife made me some asparagus about four months ago with this stuff on it... Hollandaise sauce she called it... and doctor, I'm talkin' DELICIOUS! I've never tasted anything like it, and ever since then I've been putting it on everything... meat, fish, toast, vegetables... you name it!"
"That's probabably it," replied the dentist "Hollandaise sauce is made with lemon juice, which is acidic and highly corrosive. It seems as thought I'll have to install a new plate, but made out of chrome this time."
"Why chrome?" the man asked.
"Well, everyone knows that there's no plate like chrome for the Hollandaise!"
