A soul has just arrived in heaven, and St Peter is showing him around.

They go past a banquet table where a bearded man is doing the honors with a roast suckling pig. "Those are pious Jews," St Peter explains. "They were not allowed to eat pork on earth, so they get to make up for it here."

Soon they pass a big round table with people sitting around it with steins of beer, singing hymns. "Those are hardshell baptists," he explains. "They were not allowed to drink beer on earth."

Then they find themselves walking by a formidable high wall with no gates and spikes on top. Sounds of roistering come from behind it. "Oh!" exclaims the newcomer. "Who lives there?" "Shhh!" says St Peter. "Those are Catholics. They think they're the only ones here."
