The Shake Weight may be the funniest workout aid ever invented.  Seriously.  The thighmaster has NOTHING on this...  watch the video in the following link and you'll understand. My problem with it is that I see no point in spending then $20 (+ S&H) when you can get the same workout for free and make us (your boys) happy at the same time.... you get a work out and strong upper bodies and in the end we both get happy endings! :)
