A husband and wife crawl into bed. The hubby nudges his wife and says:
“How ’bout it?”
His wife rolls over saying “Not tonight dear I have a headache.”
The next night, they go to bed and the dialogue repeats.
Third night, same thing.
On the fourth night, the wife is in bed. The hubby comes into the bedroom carrying a glass of water and two aspirin.
“What’s with the glass of water and aspirin?” asks the wife.
“It’s for your headache,” replies her husband.
“Headache? I don’t have a headache,” says the wife.
“I’ve got you now!” smiles the husband.
