This episode marks the first time we see Diane's apartment.
This was the first episode John Ratzenberger (Cliff) was cast as a regular cast member.
Cliff (about reincarnation): The Hindus believe that what you come back as depends upon your behavior in your this life. If you led a good life, you come back in an elevated state.
Coach: Like Colorado?
Cliff: No, Coach. Uh, more like a king or a prince. Conversely, if you've not led a good life, you come back in a more lowly condition.
Norm: Last time out, I must have made a real ass out of myself.
Sam: You've made my life a living hell.
Diane: I didn't want you to think I was easy.
