An elderly couple were at home at the wife called out "So, when are you going to the doctor"

"I told you, I'll go when I feel like going."

After 3 months of nagging, the old man finally walked
into the doctors office.

"Doc," he said, "This is
embarrassing, but I'd like to get a prescription for
Viagra."

"Not a problem," said the doctor, as he started to write the Prescription.

"You don't understand," said the old man. "I am almost
90 years old and I haven't had sex in more than ten
years. I only want it to stick out a little so when I
pee, it doesn't get on my shoes."
