Lyrics:

John was a metal-headed monster
He caught a piece of the earth
And sometimes he flew off the handle
And that was his handle
Jack Hammer
C'mon, c'mon good buddy
He's Jack Hammer
Jonathan, Jonathan H-A-M-M-E-R
He had a fist full of dirt
Had a shirt
He had boots
They were black
His fist came so close she had a wind attack
He's Jack Hammer
He's Jack Hammer
Mouth like a power saw
Head like a radio
Hand like a bear paw
Pants full of tadpoles
He's Jack Hammer
He's Jack Hammer
