Every Goliath Has Its David

I've got a little bag of marbles and a catapult
 Wound around my fingers and I feel very small
 But I could make myself big if I wanted to
 There is nothing courageous about anything I do
 I'm trying to balance on an upturned mail crate
 As I fumble with my catapult
 And my hands are trembling as I try to aim it
 But every Goliath has its David
 And I know Kung Fu
 And I'm not afraid of you
 'Cause I might be small
 But I'm not a coward
 I've got puppy powers
 That I'm not afraid to use
 My fists are balled up in the pockets of my anorak
 And I've got a peashooter hidden behind my back
 All I need to do is sit and wait to be attacked
 If I thought that it would make me happy then I would
 Tie a handkerchief to a stick and surrender
 But that isn't what I want to
 I will never live up to my expectations
 Every Goliath has its David
 And I know Kung Fu
 And I'm not afraid of you
 'Cause I might be small
 But I'm not a coward
 I've got puppy powers
 That I'm not afraid to use
 And I know Kung Fu
 And I'm not afraid of you
 'Cause I might be small
 But I'm not a coward
 I've got puppy powers
 That I'm not afraid to use
