Notables:
The title is a play on the phrase "A pinch to grow an inch."  Perfect for an episode like this.
Eddy has stunted growth.
Rolf is a basketball fan.

The Eds, at least Eddy, are 11 years old.
Eddy's a really high jumper, but is very weak.
MISTAKE: When doing the growth chart, Eddy realizes he's the same height as before.  The line is white, but in the close-up, the line turns black.  When the screen zooms out again, the line is again white.
Ed's head is very balanced.
