Husband and wife had quarreled for a while. After cool down period wife came back to husband in the morning and asked, "Honey what are you doing?"
Husband tried to hide the document in hand and mumbled, "Nothing!"
Wife took on again, "Nothing what? I have been seeing you are reading our Marriage certificate for whole night, even with magnifying glass, upside down, backside front, intense lamplight. What's the sickness with your brain?"
Dejected Husband said, "Nothing, I was just looking for the expiry date."
