I realize this has been done many times before but it's fun. I'm only posting because I recently spotted a new "mistake" (at least for me) in the "Mayberry Band" episode.

Towards the end Barney goes "on lookout" while the fake band is getting organized on a side street. The Mayor pulls up in his car and parks nearly in front of the bench Barney has chosen for him. In all the other shots in that sequence there is no car. The Mayor and Barney (and later Andy) all have a full view of the main street.

I also wondered about why the Mayor and Barney couldn't hear the fake band guys doing their quick practice (and the really good trumpeter doing furbalos)...but I guess maybe the sound didn't carry so I really can't count that one.

Anyway - post mistakes you know of if you don't mind - I might learn something...Thanks and Happy New Year. :)
