Hopelessly behind in the game, Left tried to think of some way to gain advantage.

"You know Right, I can prove you're not really there."

"How so?"

"You're not solid - you're made of tiny dots called pixels with space between, just like the ball. It could probably go right through you if it wanted."

Right worried until the ball DID pass through.

"In fact I wonder when your dots will just fly apart."

Horrified, Right's paddle dispersed into nothing. Left served out to win.

Lesson: Don't lose sight of the big picture on tiny details.
