Requirements: Ten Fingers Tell your friends that you have eleven fingers, and you can prove it! Using your right forefinger to point with, touch each finger of your left hand, counting "One, two, three, four, five". Then with your left forefinger count the fingers on your right hand, "Six, seven, eight, nine, ten".
Say "Funny, I know I had eleven. Let's try again". This time count backwards, pointing to the fingers of the left hand say "Ten, nine, eight, seven, six...". Then stop, hold up the right hand and say "Plus five equals eleven!". Do this quickly, without pausing!
