In an episode of Three Stooges, Curly is riding this bike that has one of the wheels with the spokes meeting off centered.. so.. not directly in the middle of the wheel, but meeting to one side of it. To ride it you *stand* on platforms and pump the platform up and down.
Does anyone know what I'm talking about? I would really like to find out if anything like this still exists! Any direction from anyone here would be extremely helpful.
