Can You Uncover the Little Known Mistake in the ‘Green Acres’ Opening?

Green Acres was a popular 1960s television show starring Eddie Albert and Eva Gabor. Watch the video and see if you can spot the little known filming mistake in the opening of the show.

If you weren't able to spot the mistake, don't worry. I've watched 'Green Acres' in both it's original run and over the years in syndication and never spotted the mistake until it was pointed out to me recently.

The mistake? When Oliver (Eddie Albert) sings "You are my wife," he reaches for Lisa (Eva Gabor) with his left hand. But when Lisa sings "Goodbye city life," Oliver is grabbing her with his right hand.
