Witches

A pat on the back and my undying admiration to the ones who can identify these quotes...

Quote A (this is really an easy one):
"Get back, witch!" "I'm not a witch! I'm your wife!"

Quote B (still pretty easy):
"She turned me into a newt" "She turned you into a newt?" "Well, I got better."

Quote C (Extra Super Bonus Challenge Round):
"That woman is a witch." "Yes, but she's OUR witch. So cut her down."

(Mikey is not allowed to guess, as he has an uncanny ability to read my mind AND he already has my undying admiration.)
