I know there are tons of different programming languages, and some of them are made with a tad of sense of humor. But which one is the funniest in your opinion?

I have heard of something called Moo (although I am not sure of the exact name), which was a programming language for the JVM. The basic idea was that the only syntax allowed was a fork of Moo, like this:

moo; //Means something
mooo; //means another thing
moooooo; //means something else

and so on. That is pretty funny IMO. Not so useful, and definitely not easy to learn, but quite funny.
