An elderly gentleman went to see his doctor and asked for a prescription of Viagra. The doctor said, 'That's no problem. How many do you want?'
The man answered, 'Just a few, maybe 4, but cut each one in 4 pieces.'
The doctor said, 'That won't do you any good.'
The elderly gentleman said, 'That's alright. I don't need them for sex anymore as I am over 90 years old. I just want it to stick out far enough so I don't pee on my shoes.'
