Straps

When I was young, my family would go to the Museum of Science and Industry in Chicago.
Back then, there was an exhibit demonstrating bell curve distributions using back balls falling through a maze of pegs and into slotted compartments.
The balls eventually formed the bell curve shape… as if by magic.
“Not magic, you little weirdo,” growled my father. “It’s mathematics.”
I pointed at the lonely ball in the two-sigma slot: “That’s me!”
My parents were shocked, and they recoiled in horror from me.
Why?
Because I’d managed to chew through my straps and my hands were free again.
