St. Peter and the Politicians
St. Peter and the Politicians St. Peter was standing at the pearly gates of Heaven When a group of politicians walked up. "Hey Petey, may we come in too Heaven?" asks one jovially. St. Peter replies "Well, we have never had a group of politicians come in to heaven before, let me ask God." He then turns around and goes to consult God. "My lord, there is a group of politicians at the pearly gates of Heaven. Should I let them in?" God thinks for a moment and says "We have never had politicians in Heaven before. Let's see how it goes. Let them in." St. Peter leaves God, only to come running back a few minutes later. "THEY'RE GONE!" He said. "The politicians?" "THE PEARLY GATES!!"
