Mine?

Once there was a married couple. The husband was in a room, looking around for something.

His wife entered the room and said "why is it that you always call everything yours - like 'my house', or 'my car' or 'my TV'. We are in a partnership - we are supposed to share. Its 'ours' not 'mine'".

The husband kept looking around as if his wife had said nothing. She then asked him "so what are you looking for?"

"Our pants" said the husband.
