@Fukcster, if said blacksmiths hammer came in a downward motion onto the plastic of the said marital aid, it would crush it like a solo cup being stepped on an elephant... if it were grasped and hit on the end, it would crumple it like a car hitting a wall... it's a matter of physics or sorcery or gravitational coefficients from the mind of Sir Isaac Newton.
@Locket44 was no doubt in jest, as the on/off switch would have been the more appropriate methodology; she was just trying to lure suitable victims to her chambre à coucher principale, as it were.
Good point @ThePyrate, but, in this situation seems like one end is INSIDE, so downward motion do the trick, but hitting on the end, especially if not grasped tightly enough, might send it IN?
