As close as Barney and Andy were, was there ever an episode ( apart from the one in color when Barney comes back to Mayberry for a visit ) where Barney stayed overnight at the Taylors ?
I don't think Thelma Lou or Goober ever did, but Otis ( as a prisoner ) and Gomer both stayed over.
Helen certainly never did, that would have been most inappropriate !
Then there was Andy's cousin and a couple of Aunt Bee's "beaus."
Any more I missed other than some of Opies buddies ?
There was Uncle Ollie and Aunt Nora with their boys.
There was that poor little baby that kept getting stuck by Aunt Bee's pin.
Cousin Gloria stayed with the Taylors to get over her broken heart.
