Worthless Inventions

I got an email yesterday listing the following as the most worthless inventions:

The water-proof towel
Glow in the dark sunglasses
Solar powered flashlights
Submarine screen doors
A book on how to read
Inflatable dart boards
A dictionary index
Powdered water
Pedal powered wheel chairs
Water proof tea bags
Watermelon seed sorter
Zero proof alchohol
Reusable ice cubes
See through tiolet tissue
Skinless bananas
Do it yourself roadmap
Helicopter ejector seat

I thought to myself, "Monkey Barners can do waaaaaaay better than this."

So C'mon, Monkeys! Can you think of a more worthless invention?
