Chorus:
           Gravity is pulling down,
           Pulling down, pulling down,
           Gravity is pulling down
           All around you!

           Take a ball and toss it high.
           Will it stay in the sky?
           Gravity will pull it down
           All around you.

           Chorus:
           Gravity is pulling down,
           Pulling down, pulling down,
           Gravity is pulling down
           All around you!

           Jump up high and down you'll go.
           There's a force down below.
           Gravity is pulling down
           All around you.

           Chorus:
           Gravity is pulling down,
           Pulling down, pulling down,
           Gravity is pulling down
           All around you!

           Push, push, push your cart,
           Gently through the store.
           Fill it full of lots of things,
           Then let's add some more.

           Pull, pull, pull your sled,
           Gently through the snow.
           Let's get on and zip on down.
           How fast can we go?

           Push, push, push the boat,
           As the wind does blow
           Over the ocean and into the sails,
           To make the sailboat go.

           Pull, pull pull the flag,
           As the wind goes by.
           Pull the flag to make it flap,
           Look how proud it flies!

           Push, pull, to make it move,
           Try it and you'll see.
           Things move with a push or pull-
           Even you and me!

           If you want to move a ball
           from here to over there,

           You can kick it with your foot
           and send it through the air.

           If the ball's too heavy,
           don't you despair.

           Make a ramp, sent it rolling.
           It will get over there.

           Push it or pull it.
           Move it everywhere.

           Roll it down, throw it up,
           high into the air.

           Try a magnet or a lever
           and your moving will improve.

           Rubber soles?  I understand,
           They're there so I don't slip.
           Lots of lace?  I understand,
           They're there so I won't trip.

           Nice high tops?  I understand,
           They're there so I won't wobble.
           Arch supports?  I understand,
           They're there so I won't hobble.

           Red or blue?  I understand,
           These match my running suit.
           Stripes or dots?  I understand,
           They're fun, they're weird, they're cute.

           But "sneakers"?  I don't understand.
           Were they really designed for sneaking?
           Basketball sneaking? Or tennis sneaking?
           It confuses me, in a manner of speaking.

           Michael built a bicycle
           unsuitable for speed,
           it's crammed with more accessories
           than anyone could need,
           there's an AM-FM radio,
           a deck to play cassettes,
           a refrigerator-freezer, and a pair of TV sets.

           There's a desk for typing letters
           on his fabulous machine,
           a stall for taking showers,
           and a broom to keep things clean,
           but you'll never see him ride it,
           for it isn't quite complete,
           Michael left no room for pedals,
           and there isn't any seat.
