Yes, it's a Very Nice Picture!! I remember a couple of Christmas themed episodes of Bewitched too! But, I don't think I've seen "Sisters at Heart"?

I see Why "Sisters at Heart" was your favorite episode!!
"Long before "Very Special Episodes" became a part of our television vocabulary and one year before the groundbreaking "All in the Family" debuted, "Bewitched" switched gears and tackled the daring and innovative challenge of confronting racism -- something almost unheard of in the sitcom world of 1970. Written by 10th grade high school students (with assist from Barbara Avedon & Bill Asher) it superbly gets the serious message across in a sturdy yet charming manner while still fitting into the standard "Bewitched" formula.
When asked what her all-time favorite episode was, Elizabeth Montgomery cited this as it and was even quoted to say that "this is what I want "Bewitched" to be about." Indeed the message is so strong that it stands more on its own as a pioneering episode rather than a Christmas episode, which in the past simply dealt with the typical fare of Santas and Scrooges."

Yes, I also Enjoyed the sexy pictures of Santa Samantha too!!! ;-)

Merry Christmas To You My Friend!!!!!! :-)
