Tappity Tappity

Sheldon's dance career would soon be cut short when his father told him tap-dancing was "sissy stuff," and moreover, you needed shoes to tap and he wasn't about to fork over the soup money for frivolities.
But Sheldon COULD tap.
Ever since the day he walked on those tacks.
He didn't need SHOES! He could tap on his own! He was free! Free, I say!
