The crank is coffee and it goes all the way around. The rocker is work and it only goes back and forth, forever. The coupler is you, tracing the same loop every Tuesday. A Grashof crank-rocker four-bar linkage with its coupler curve, and the math that proves the short link is the only one that gets around.
