Good Idea?

[LANDROVER ROGER]

An elderly gentleman visits his chemist and asks to buy some Viagra.When the pharmacist hands them over the old chap asks him to cut each tablet in to four equal pieces.The pharmacist says that he can do that but warns that the smaller dose will not have the full effect normally required.The old chap replies,"That does not concern me.I just want it sticking out far enough to stop me p*****g on my slippers".
