Love karaoke, but hate the sound of your singing? Do friends point and laugh when you attempt a warble? Why not buy the Noiseless USB Karaoke Mic for the Wii? They'll even throw in a set of free steak knives!*
It works by plugging into the Wii, or a laptop running Vista or XP, via USB and absorbs some of your singing in the cone-like muffler around the microphone. Found at the Japan Trends shop for $84, it's probably snapped up by the same women who bought those keyrings that play thunderstorm noises when they're on the loo. [Japan Trends via Technabob]
