A church has a rat problem
The church doesn't want to kill the rats so they trap them and release them far away, but the next day they are back.
Next they try ask them politely to leave, still they won't budge.
Finally the priest has one last idea, he baptized all the rats.
Now they only come at Christmas and Easter.
The synagogue had the same issue with rats and decided, like the Catholics, that bringing them into the faith was the only solution. They had a better end result... after they circumcised the first one the rest vanished!!
