At the Pearly Gates, he says, "St. Peter, I'm ready to go in." St. Peter says, "Not so fast; we have special rules for special people like you. First, you must spend a day in Heaven, then a day in Hell. When you come back here and decide where you want to be, we'll send you there. The Senator finds Heaven tranquil, even sublime, where everyone floats on clouds singing and playing the harp. In Hell, he finds all his deceased colleagues partying while drinking the finest champagne and eating the finest caviar and lobster. He parties hardy with them the whole day. Back with St. Peter, he complements Heaven but decides to spend eternity in Hell. When he gets back there, he finds a proverbial wasteland where his colleagues are miserable, wearing rags, and picking up garbage as it continually falls from the sky. The Devil comes to him and puts his around him, saying, "Welcome to hell." Very upset and confused, the Senator tells him what he saw yesterday when he was there. The Devil explains, "Yesterday, we were campaigning."
That about sums it up! There was a "Twilight Zone" (original) along those lines. The guy didn't want to go wherever he couldn't take his dog.
