Me: How long has the Oil light been on on your car?
Mrs Wife: Oil Light?
Me: Oil light! (Pointing)
Mrs Wife: Oh that! A couple of weeks...(50 miles or so) I thought it was a watering can?
Me: Why would you need a "watering can" warning light?
Mrs Wife: For when the car needs cleaning, but I didn't think it looked too bad so I didn't worry about it...
Me: OK, we better stop at the next garage and top up the oil.
"For when the car needs cleaning" !!!! bless her. I was having a crappy day until I read that I feel much better after a good giggle
