Well-actually this was in my synnaguge. I was about 5 or 6 and there were these stained glass windows on the walls featuring the Jewish holidays and the twelve tribes of Israel. Well there was the one of Joseph-which is represented by a tree, and because the tree had sphere shaped fruit of green, pink and purple (dispite not being an evergreen) I concluded that it was a Christmas tree. So I happily shouted "Mommy, Christmas tree!" and she told me to shush.
I still find this to be delightfully funny.
