I am sure you have all been there.... topped off my cart a little too much or too many times over and eventually it dropped out the blow hole of the cart. I about drove off the road...quite the burn. I though maybe I sucked it all out... another drag....another drop on the tongue. Yes, now my lounge is numb I wonder how many of those it would take to get nic poisoning.. I would imagine "a few"... Note to self, don't top off so much and wash cart more often already. Bman.
