2 good Unitarian Jokes:
What do you get when you cross a Unitarian with a Jehovah's witness? People who knock on doors for no apparent reason.....
Sign on the Unitarian tombstone.....All dressed up and no place to go.....
One b-i-l used to call Unitarians "Atheists who haven't kicked the Church habit". My Jewish b-i-l called Reform Jews, "Atheists who haven't kicked the Temple habit".
