Ryan McFarland, soon to be known as Lord of the Homeless, took the front tire off his bike and replaced the damn thing with a shopping cart. Apparently its steering is limited, which is no surprise, but who cares. It looks sweet and you can haul at least eight or twelve cases of beer on that thing. There is an instructables guide if you're interested, although I think you get the gist of how it was done. Just make sure not to steal one of those crappy buggies with wonky wheels. If you don't the only hauling you'll be doing is your ass to the hospital because you slammed into a parked car.
