One'S Tail Does Duty As...

A long tailed monkey's tail does duty as his hand
A fox's tail does the office of a rudder
Owing to the tail, lizard can make good her escape
Cattles shoe files with their tails
Dogs are glad with their tails
And pig's one draws a circle
How about us?

We have no tail
Because it is of little avail
and we are in great trouble without drawers
But to tell the truth, nobody knows how to use the tail
