The Spider Pool Trainer
If you're sick of getting your ass kicked at pool by that smelly dude at the bar, then order yourself the Spider Billiard Training Device ($80) and score some alone time with the nearest table. The gadget uses laser beams to show you exactly where you need to target in order to make the shot and set yourself up for the next. The Spider will help you improve your game so you can hold your head high after the next time ol' boy challenges you.
