Colour Blind

A life being colour blind is not very funny because
All people want us to do, is tell them what colour is blue
Or green or red or brown, of which all you can do is frown
‘Cause you know you won’t get it right, which leaves them laughing all night
How cruel was the person to ask, and give us the impossible task
Would you ask a cripple to run, and then when they couldn’t make fun
Well no, because that would be cruel, as would making us look like a fool.
