Sung to the tune of "Puff the Magic Dragon" - See post below for more ideas.
Mitt the Magic Monster lived by the sea.
He fleeced old ladies Medicare till they lived in misery!
He told them he'd take care of them. He promised cake and tea.
But when they opened up their plan, it had nothing there, you see!
Mitt the Magic Monster, craven, weaselly...
Lying, thieving and deceiving
Nothing more is he!
