It's a Greek Life

Mercury, the winged messenger, drops his sandals off with a centaur to be repaired. The centaur, who has coveted wings to the extent that he's used a couple ducks to help him fly, takes the sandals for a spin, and fails to finish the repair job on time. Mercury returns; in a panic, the centaur strips the wings from a couple birds and nails them to some plain sandals, but Mercury is not fooled. He turns the centaur into a pretzel.
