You shouldn't be from the northeast. This is a dialect, which means that this person is very economical (stingy) to eat a string of mutton skewers and drink eight bottles of beer. Finally, the drill is full of sparks, which means that the teeth or mouth rub against the drill (in order to thread the string) and produce sparks. Personally, it's not funny. I can drink eight bottles of beer. Is it still economical?
