When Samantha met Sheila
I always liked the episode where Samantha gave Darrin’s old girlfriend her comeuppance.
What I like the best was Samantha’s mannerisms when casting a spell on Sheila. When she wanted to mess up Sheila’s hair Samantha would stroke her own hair. When Samantha blew a candle out it was a spell to conjure up wind.
I wish they would’ve used these type of mannerisms in later episodes when Samantha did witchcraft. I think it was interesting and it brought some variety instead of her always twitching her nose.
