Pills

A woman walks into her sex therapist's office and tells her that her
husband is not a very good lover, and they never have sex anymore, and
asks what to do about it.

The therapist tells her that she has an experimental drug that might do
the trick. She tells the woman to give her husband one pill that night
and come back in the morning and tell her what happened. 

The next day, the woman comes in ecstatic telling the therapist that the
pill worked and she and her husband had the best sex ever. She asks her
therapist what would happen if she gave her husband two pills and the
therapist says she doesn't know, but to go ahead and try it. 

The next day, the same thing happens, the woman comes in telling the
therapist that the sex was even better than the night before and what
would happen if she gave him five pills. The therapist says she doesn't
know, but to go ahead and try it. 

The next day, the woman comes in limp but happy, and tells the therapist
that the sex just keeps getting better and what would happen if she gave
her husband the rest of the bottle. The therapist says she doesn't know;
it's an experimental drug and she doesn't know what 
a full bottle could do to a person.

Anyway, the woman leaves the therapist's office and put the rest of the
bottle of pills in the husband's morning coffee.

A week later, a boy walks into the therapist's office and says: "Are you
the dumb fuck who gave my mother a bottle of experimental pills?" 

"Why, yes, young man, I did.  Why?" 

"Well, my mom's dead, my sister's pregnant, my ass hurts, and dad's
sittin' in the corner going 'Here, kitty, kitty, kitty'."
