I Can Do That
[MIKE]
I'm watchin' 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 grab her shoes and tights and all
But my foot's too small, so
I stuff her shoes with extra socks
Run seven blocks
In nothin' 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..."

[An extended tap and acrobatics routine finishes with an aerial back-flip, landing with a flourish.]
That I can do!
I can do that!
