Where was the telephone on the Douglas farm in Green Acres?
The Douglas family does have a phone, but, unfortunately, the phone company ran out of wire, so the phone exits, but doesn't work. Oliver, of course, is not going to take it for granted. As luck would have it, Oliver finds out that Sarah, the owner of the phone company, is Mr. Kimball's mom, and asks Mr. Kimball if he could help get their phone hooked up. Even though Mr. Kimball and his mom don't talk anymore (Because she wouldn't let him get a dog a week ago), Mr. Kimball agrees to bury the hatchet with Sarah.
Sarah is so grateful that Oliver has gotten her son to talk to her again, that the next day, Oliver and Lisa find themselves with a brand new working phone... on top of a pole...outside their bedroom window. Isn't that nice?
