A man walks into a diner. The waitress comes over with some coffee and a menu. "What'll it be?" she asks.
The man thinks it over for a bit and decides on eggs Benedict. "Coming right up," she replies.
A few minutes later she returns with his order.
"Thanks," the man says. "This looks delicious, but I have to ask. Did you run out of plates? Why are my eggs on a hubcap?"
"We always serve it this way," the waitress patiently explained, "Because there's no plates like chrome for the hollandaise!"
