Shoveling job

Teddy earned a buck every time he shoveled the driveway.
So, he shoveled the driveway five times a day.
Even in the summertime.
“That’s not how it works, Teddy,” said his dad. “If you want to earn more, go shovel other people’s driveways.”
So, Teddy did. And he came back to his dad looking to get paid.
“That’s not how it works, either,” said his dad. “They need to pay you for shoveling their driveways.”
So Teddy attacked his dad with the snow shovel.
Now Teddy shovels the driveway at the reform school.
And they don’t pay him a dime.
