Black Jack the goat spent his time in the wings, learning the tricks of the late, great Jumpy. Where did Jumpy learn? Some say he was highly food-motivated. Some say he trained himself. Some say he was abducted by aliens and came back a changed goat (no one actually says that). Now Black Jack has stepped into Jumpy’s hooves and carries on the proud tradition, which begs the question: was Jumpy murdered so that Black Jack could get all of the fame and goat kibble he desired? No one’s asking that, either.
