An old man goes into a drug store to buy some Viagra.  ‘Can I have 6 tablets, cut into fourths or quarters?’

‘I can cut them for you ‘ said the pharmacist, ‘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 pee on my slippers.’
