Inverted and parodied in The Bob and Tom Show's recurring "Mr. Obvious" skits. The premise in them is that Mr. Obvious, a the host of a radio call-in show, attempts to help today's caller with what looks to be a difficult problem until the caller reveals enough facts about his problem to make it clear that he has no clue, he can't afford to buy one, and he refuses to rent-to-own, and that the caller would have solved his problem by himself long ago if he weren't so bloody dense.
Subverted in the "Sump Pump" episode, where the terrified caller tells Mr. Obvious that there's a bear under his house, and every time it rains he can hear it growling. Mr. Obvious has to explain that this is just the sump pump, pumping water away from the foundation.
