This is a joke I heard around 25 years ago:
A woman moved to a new town and her neighbor visited to welcome her to the neighborhood. At some point the neighbor asked, "are you a Catholic or a Protestant?" The woman answered, "actually, I'm an agnostic." Her neighbor replied, "that's okay, dear, we all pray to the same God."
A neighbor once invited me to their church send I told them "thanks but I'm Jewish" and they said "what's that?"
Liked that one. On the subtle side, but definitely a winner. Thanks for the chuckle, resserts.
