Race

'Nice day for the race'

What Race?

'The Human Race. But don't worry, you're not in it'

Just not funny.

Dark

Trying to explain something to a colleague you might say 'at the end of the day....'
However before you can finish your sentence they might pitch in with...

'It get's dark'

Yes. The Sun won't be rising for you again.

Name

To attract someone's attention You might call their name
They might reply

'That's my name, don't wear it out.'

What shall I call You then, an Ambulance? You're going to need one when I'm through with You.
