Fingers

Fingers hold your sandwiches
And fingers scratch your head
And fingers pick your nose
When you're lying in your bed
Fingers play piano, trumpet or guitar
And fingers make rude gestures
When you're driving in your car
So don't cut off your fingers
They do useful stuff for you
And you might find your lover

Enjoys your fingers too
But if you let your knife slip
Because you are in a hurry
Fingers are quite tasty
If you cook them in a curry
