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 the pharmacist,' but a quarter tablet will not give
you a full erection.'

'I'm 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.
