Persistant Stoner

A stoner walks into a 7-11 and asks the clerk "got any weed?" the clerk responds "Hell no you damn stoner". The next day the stoner returns he asks the clerk "got any weed" the clerk outraged smashes the stoners head on the counter and says, "Look you stoner if you come in here and ask if I got weed one more time I will nail your feet to the floor" So.. the next the day the stoner walks in and asks the clerk "got any nails" the clerk says no... so the stoner asks, "got any weed"?
