A man got a prescription for Viagra, and went home to get ready for when his wife got home.
He called her on the phone, and she told him, “I’ll be home in half an hour.”
This was perfect for the man because the Doctor told him to take his Viagra half an hour beforehand. He took the Viagra and waited.
The half hour went by, the man was ready to go, but his wife was a no show. He called her cellphone and she informed him, “Traffic is terrible. I won’t be there for another hour and a half.”
Out of frustration, the man called his doctor for advice.
The Doctor replied, “I suppose it would be a shame to waste it. Is your housekeeper around?”
“Yes, she is.” the man replied.
“Well, maybe you could occupy yourself with her instead?” said the Doctor.
A bit dismayed, the man replied, “But I don’t need Viagra with the housekeeper.”
