I completely forgot to have a look at ThinkGeek's April Fool's lineup. Usually some of their April Fool's products make it to production (and some are actually just jokes). I picked three of my favorites.
Back in the 90s it seems that many people thought that there was a movie called Shazam with comedian Sinbad (so much so that Snopes I think has an article on it). I guess it's time to make this happen if so many people think it existed ;-)
I think this is my favorite of them. I don't know why it's plugged in (it seems like a hazard) but piggybacking on the standing desk and treadmill desks fads...why not a swim desk?
