I'm going to teach them a lesson: Is there another way?
It's wet out: Is it ever wet in? (non-sexual, please)
I'm going out of my mind: How do you go in your mind?
I'm at my wits' end: How can you know where it or they end?
At the end of the day: Why not before tomorrow?
They don't call him clever for nothing: How much does he have to pay?
It's gone pear-shaped: Why not banana, or g-string. What's wrong with the shape of a pear?
He's a mummy's boy: Is there another form?
I could go on forever - but actually I can't!
