From IMDB.

So so ep here. Ozzie and the family get into a tizzy about a street corner that doesnt have a signal. Each family member has their own way of dealing with this. Harriet talks to the women's club, Ozzie goes down to city hall etc. Soon one IS installed, and they're fighting over who should get the credit. Even Thorny and Oz get into it.. Probably the most argumentative I've seen them in. Somehow at the beginning, George Washington's Birthday is thrown in at the beginning then dropped.
As the previous reviewer has said, this has been edited down. This COULD be because of Syndication, but I'm not sure. The beginning is different, no sponsor mentioned, and there are different end credits. What baffles me though is that one joke conclusion, with the basketball. That never existed in previous episodes.. bah..

Man, This episode is an edited print, missing 4 minutes of the show itself, along with 3 minutes of commercials.
