I'm watching Sis
Go pitterpat

Said
I can do that

I can do that

Knew every step
Right off the bat

Said
I can do that

I can do that

One morning Sis won't go to dance class

I grabbed her shoes and tights and all
But my foot's too small
So
I stuff her shoes
With extra socks

Run seven blocks

In nothing flat

Hell
I can do that

I can do that

I got to class
And had it made

And so I stayed
The rest of my life

All thanks to Sis

Now married and fat

Said
I can do this

That I can do

I can do that
