One of the greatest Simpsons episodes all time was Oh Brother, Where Art Thou?, famous at the time for Danny DeVito's cameo as Homer's brother Herb, but more famous now for the legacy of the car that stole the show. Asked by his brother to design a new car, Homer comes up with... The Homer, a car that has everything. Except design sense.
Which hasn't stopped Porcubimmer Motors from paying tribute to the car by building their own, which while not an exact replica, is about as close as you'd get without having to start from scratch.
