Joke on Rails

Just inside the gates of heaven, St. Peter sits at a desk checking people in.

Peter: .Welcome to heaven. Programming language?.

The man at the front of the line says, .Smalltalk..

Glancing at his clipboard, Peter says, .Room 33. Be very quiet as you pass Room Six..

The process repeats itself with the next person in line:

Peter: .Welcome to heaven. Programming language?.

Person #2: .Common Lisp..

Peter: .Room 17. Be very quiet as you pass Room Six..

The next person moves to the front of the line with a look of curiosity on her face.

Peter: .Welcome to heaven. Programming language?.

Person #3: .Python..

Peter: .Room 54. Be very quiet as you pass Room Six..

Person #3: .Why do you keep telling us to be quiet as we pass Room Six?.

Peter: .Because the Ruby on Rails People are in Room Six, and they think they're the only ones here.
