One laugh to little//

An old man goes into a chemist to buy some Viagra.

'Can I have 6 tablets, cut in quarters?'

'I can cut them for you ' said the chemist
' but a quarter tablet will not give you a full erection. '

' I am 96 ' said the old man .
' I don't want an erection .

I just want it sticking out far enough so I don't piss on my slippers. '
