My mother
Mum "The wheel trims on my car are upside down"
Me "How do you mean?"
Mum "The nissan sign is facing down"

When hearing that her friends car had been broken in to:

Mums Friend "...They didn't take much, just some of my tapes and some books i had on the back seat. Although strangely they left the money"

Mum "you mean they paid for the stuff they took?"

A little different but... A friend of mine was commenting on his aches and pains after playing football:
Friend "i have the back of a 60 year old"
Me (half listening) "you have to bath a 60 year old? why?"
