85 year old man goes to the doctor:

Hes says "Doc, I vant you should give a 1/4 pill of Viagra."

Doctor syas to Harry, that its great that you want Viagra, even at your age sex is a healthy thing...But you will need a full pill.

Harry says...No I just vant the 1/4 pill...
Its not about sex....just want to get it up enough so I can stop peeing on my shoes.
