It would never occur to me to hold a mouse under running water, but that's why I'm not a marketing genius like the good folks at Belkin.
They just released a press announcement trumpeting the fact that they've developed "a water-resistant mouse that can survive spills and can be hand-washed under the faucet to stay clean and disinfected."
Doesn't this picture look like it came off a Saturday Night Live skit? "Mouse-Soap – the miracle cleanser that washes your hands AND navigates your spreadsheets!"
All this waterproof goodness can be yours for $29.99 USD.
