Hey!

Hey diddle-e-dee, a Sunday working spree!
Hey diddle-e-oh, it's off to work we go!
Sometimes on weekends it is fun
To be here all alone
There's no one here to slow you down
The business is your own! (Or so it feels like)
Hey diddle-e-dee, productivity!
Hey diddle-e-oh, sometimes it's fun, y'know!
