Ernie and Bert: Shape Sides

Ernie lies in bed and starts talking about how a square looks and how many lines it has, then goes on to compare a square with a triangle. And then starts to ponder about how many sides a circle has, and goes to sleep just as Bert is about to attempt to answer the question, and ends up not being able to sleep.
