Mad Magazine had (or maybe still has) an occasional section called "Snappy Answers to Stupid Questions." I just ran across this that made me think of it:
A photographer went to a socialite party in New York. As he entered the door, the host said, "I love your pictures -- they're wonderful; you must have a fantastic camera." He said nothing until dinner was finished, then, "That was a wonderful dinner; you must have a terrific stove."
