Jerry Bernard is one of Harrison Walker's uncles. He gave Harrison a pocketknife for his twelfth birthday. Jerry is known for using liberal amounts of hot sauce on any food and drinks he consumes.

“But you know, my uncle Jerry actually does order coffee with hot sauce drizzled on top. And that’s not even the strangest thing he eats. He’ll put hot sauce on everything, really. He even ruined a perfectly good apple pie I made last Christmas by dumping half the contents of his personal hot sauce bottle on top.”
