Along an icy winter sidewalk, edged by snow banks on either side, a little girl, walking with her mother and brother, slips and falls. Her equally little brother looks at her and says “Walk it off! Walk it off!” He offers his hand, she refuses.

She stands up wearily but is still visually upset by the tumble. This time her bother says, “Shake it off!”

And when that still doesn’t work, he just starts listing things “Twist it off! Throw it off! Screw it off!” Then in all seriousness he stops and says, “But imagine if you really unscrewed it so much that your hand fell off?”

They both stand for a moment looking at each other, imagining.

Then the streetcar pulls up and the little brother says “OOooH, it’s a double one!” And the little sister echos “A double one! A double one!”
