I've always liked this one, because I think it says a lot about how we think of each other and our differences:

Comical Folk

In a cottage in Fife lived a man and his wife
Who believe me, were comical folk.
They both saw with their eyes, and to people's surprise
, Their tongues moved when ever they spoke.

Whenever they'd sleep, I'm told that to keep
Their eyes open they could not contrive.
They both walked on their feet, and 'twas thought what they eat
Helped, with drinking, to keep them alive.
