Lisa's Pony - S3-E8
Corrected entry: When Homer is on the phone with someone in his work station, (I think it's Lisa) he's talking on a phone that's connected to his work panel. When he turns to his right, there's another phone connected to the wall. Why would one person need two phones?
Correction: One closed-circuit intercom for calls made inside the plant, and one regular phone. For instance.
