A woman goes to her doctor and tells him that she can't get any sex from her husband. So he gives her some pills and says "they are experimental pills, put two into his coffee and see what happens.

So she does and the next morning come back and says "the sex was great what if I use ten?"

And the doctor replied "they are experimental pills so try it and see what happens.

So the next day she comes back and says "the sex was better, can I put the whole bottle in and see what happens?"

The next morning a little boy comes in and says, "my mother's dead, my sister's pregnant, my arse hurts like hell and my father is sitting in the corner saying "here kitty, kitty, kitty, kitty."
