What is your unsellable genius idea?

It seems that everyone has a ridiculous commercial product rattling around in there brain. Ever see the awful show ‘Shark Tank’. What would yours be?

Mine always seem to revolve around condiments.

Examples:
1) Condiments with a generous portion of caviar mixed in for the people with Mustard tastes and caviar dreams.
2) A vibrating phallus shaped mayonnaise dispensers for folks that like to make sandwiches in bed.

Have at it.
