Alice: "What are you doing?"
Dilbert: "Carpet fishing." "It's a sport I invented." "I divided the carpet in my cubicle into a numbered grid." "Then I wrote a computer program that randomly picks a carpet location and a type of fish about once an hour." "If it picks the carpet location where I happen to be dangling this string, it means I hooked a fish." "Yesterday I caught a marlin." "Did you come here for some reason other than to spoil the salmon run?"
