Season 2 episode 1
Anne begins teaching Jerry to read. She takes an alphabet needlepoint to him, sets it down and proudly says to him "Wallah!"
It ripped me out of the time period. Someone like Anne, being quite well read would know that the word she wanted is "Voilà". Canadians absolutely know this even those who dont speak French are very used to seeing French words mixed in. Such a small thing to notice, but I have to wonder how this made the final edit? Not one person was like "hold up. Did you just say "Wallah?!"
