What do you think about this Joke?

a woman walks into a blonde's house (the woman is a friend) and she sees copious amounts of "dulcolax" boxes on the floor. after walking around some more, she finally finds the blonde. she notices that the blonde is putting the dulcolax pills in a mortar and pestle and grinding them up, then sprinkling the powder onto a chair, and just sitting there, watching it. the woman walks up to the blonde and asks "what the heck are u doing!!?!?" the blonde replies, "well, on the back of the box, it says that this thing is supposed to be a stool softener, but so far nothing's happening!"
