It's friday, and an elderly man goes to his doctor for some Viagra. He asks him for a couple extra because he has 2 dates. The doctor warns him about taking too much, but decides to gives him the pills, and asks him to come back on Monday for a check-up.

The man says that there's nothing to worry about, and that he'll keep his promise to return on Monday.

On Monday the man returns with his right arm in a sling.

The doctor asks "What happened?"

The man replies, "My dates never showed up".
