(Darrin just sent down a paper flier and got a pencil, flying by magic, back)
Samantha: Darrin, before you get angry. Please be fair. You sailed something down to me, right? It was only fair, that I sail a little something back up to you.
Darrin: (argues) What I did was not only extremely clever and humorous, it was aerodynamically sound. What you did, was witchcraft. (edit) (Samantha just made it possible that all the items in the house cooperate with Darrin, she encourages him to give it a try)
Darrin : (with a strong voice) Banana... come! ...Darrin.
Samantha: You don’t have to sound like Tarzan.
Darrin: Well I never talked to a banana before. (edit)

Samantha cries real tears in this episode. Yet according to Bell, Book and Candle, the movie that inspired Bewitched, witches do not cry. (edit) If Samantha can turn back time to correct a situation, why not more often when in a tough jam. Making Samantha this powerful for one episode is a plotting error that makes other plots less believable. Only a few episodes ago, Samantha can only do small things with her magic. (edit) Humans cannot perform or learn witchcraft. That’s frequently mentioned, particular in The Joker is a Card. However, in this episode, Samantha casts a spell such that the house, and all that is in it, cooperates with Darrin and his wishes. So he is able to do magic without destroying the consistency. (edit) This episode includes one of the rare moments when Endora addresses Darrin correctly by his first name and when Endora and Darrin were nice to each other. (edit)

A Is For Aardvark very possibly refers to the first entry in the old grade school readers used to teach students the alphabet. (edit)
