Many people don’t get it.
An old man goes to the doctor for his annual checkup. Finishing up, the doctor asks if there is anything else.
The man says, “why yes Doctor, there is. I want a prescription for 1/4 of a Viagra tablet.”
The doctor tells him, “Sir, normally we prescribe in much larger doses if you want to make it.”
He replies, “At my age I only want to make it past the toe of my shoes.”
