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!”
