Mine was from ep #114, Season 4, "Birdies, Bogies & Baxter", to improve Darrin's golf game...

Endora:

"Eye of newt & scale of fish,
Give this mortal his stupid wish!
Let those clubs that he did aim,
Give him back his college game!"

Then Endora cackles and pops out. :lol: :lol: :lol:

"bees knees and bells nells return this mortal to his former state, if this doesn't work I simply can't wait".....Endora pops out, I don't remember which episode it's from, but it's my favorite.

Sam to Endora in pilot episode:

"One re on re ickery ann
filloson follison nichoulas john
queevy guavy English navy
Stickem stagnum buck
B-U-C-K spells buck and out goes YOU!"

Another one Sam used to bring Endora back (in 'Eye of the beholder" Season 1)

"Quadramus invecta expedia!"
