One of the plots of an episode of the original Twilight Zone had an old man and his hound dog walking along a country path. They came upon a man at a big fancy gate who claimed to be Saint Peter and tried to get the old man to go in to what he called "Heaven" The gatekeeper refused entrance for the hound dog, however, so the old man decided that if he was dead, he didn't want to spend eternity without his faithful old pal, so he refused to pass through the gate and went walking on down the road. A mile or so later he came upon another man, who was guarding a very simple gate. Yep. That was the real Saint Peter. Who said not only was the dog welcome, but he really didn't want anyone who would leave their dog outside the gates.
Loved that episode.
