Can you actually charge a battery by rubbing it on something?

An old teacher of mine in highschool said when he was young he used to put the batteries on the oven to get a few more minutes out of the flashlight.

I imagine it worked better with old heavy duty type carbon cells.

So no one actually thinks it's a static electricity thing?

Even if one were talented enough to be able to divine the static electricity to the charge goes to the appropriate pole (!) I would imagine it would require a whole lot of rubbing! You'd have to put the cell in your pant pocket and rub all day to get any appreciable charge, but you might be hauled off to jail under presumption of lewd and lascivious conduct.

Are you rubbing the battery across the terminals of a charger?
