Just a little sketch.
ANGEL GABRIEL KNEELS BEFORE MARY, WHO LOOKS TOTALLY SHOCKED.
GABRIEL: Do not be afraid, Mary. Religion can work miracles nowadays. [HE HANDS HER A SMALL FRAMED PICTURE.] This is how He is going to look like.
MARY: Are-are you sure it's me who...
GABRIEL: Of course. (SILENTLY TALKING TO HIMSELF) God knows how difficult it was to find a proper Virgin.
MARY: It's just that...
GABRIEL: Like I said, you will conceive in your womb and bear a son, and you shall call His name Jesus. He will be great and will be the first mammal to be conceived without male sperm.
MARY: But...
SHE HANDS THE PICTURE BACK TO HIM.
GABRIEL: Oops, actually, this will be the second one. Do not be afraid, Mary. The Son of the Most High could not possibly be born a sheep.
Personally I'd trim the end
