Amazon.com: The Fist
Amazon.com knows that a description is not necessarily needed for a product called “The Fist”? I decided to skip the visual aid… How hard is it to visualize a fist?
I think the “user reviews” are the most entertaining:
The Fist is the dandiest way of using the Carpool lane I’ve found! With the seat down and a baseball cap on the back of the passenger seat, the fist out the window looks just like my old buddy Steve.
There were few other comments left by “users”. Feel free to peruse at your own discretion.

Those comments on there are soooooo funny!!!
The one about the dirty sanches stick on mustaches is hilarious.
