Not Mechanically Inclined

Sam's wife, Ethel, came home yesterday and said, "Honey, the car won't start, but I know what the problem is."

Sam asked her what it was and she told him, "It has water in the carburetor."

Sam thought for a moment, then said, "You know I don't mean this badly, but you're not that mechanically inclined. You don't know the carburetor from the radiator."

"No, there's definitely water in the carburetor" she insisted.

"OK, Honey, that's fine, I'll just go take a look. Where is it?"

"In the lake."
