Call me (over and over and over and over)
Who woulda thunk it. I learned from a colleague that you can actually turn your cell phone into a vibrator! Vibelet.com will "Instantly turn your cell phone into a discreet vibrating personal 'masseur' - turn your phone's vibrations on at will!"
For just $4.99, that's cheaper than other toys out there! Sadly, it only works on a limited number of cell phone brands - so you may have to switch carriers to get the "full effect." But, hey, it gives a new meaning to the term "sticky keys."
