Two Little Blessings

S1, E23: Forty years before the pilgrims' journey to India, two lovers Chun-Ying and Yu-Lee disobey the God of Fertility Ju-Lee by eloping together - love is forbidden in his country. As punishment, he separates them and turns the young Yu-Lee into an old woman, the Keeper of the Well of Small Blessings. To regain her youth and her man, she must make Tripitaka drink the magic water. Things get very strange indeed when Pigsy and Sandy drink the water and become pregnant.
