To save Tom Haverford from becoming the new Jerry of the office, Ron Swanson re-hired the real Jerry back part time.
Ron Swanson:
“Are you hearing me, son?”
“Jerry will come in once a week, and everyone will get to watch him eat, and get to talk to him about anything he might do, or say, or fart.”
Tom Haverford:
“Welcome back, Jerry!”
