This is St Matthew's in the City, Auckland's billboard for Christmas 2011 (H/T Taonga):
Compared to other years and their provocative "let's see how many fellow Christians we can offend" billboards, this get's 10/10 for sensitivity to fellow Christians: Mary was really pregnant and it was a surprise to her.
St Matthew's are looking for captions. Here is mine:
"Now I am in trouble. Joseph told me to trust the angel and not waste money on a test kit."
