An old man goes into a drug store to buy some Viagra
'Can I have 6 tablets cut in quarters?'
'I can cut them for you' said Dan the farmacist'
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'
