Matsumoto and Wall and van Rossum
One day were dissecting a 'possum;
But they found that his wetware
Was all based on Netware
And so they decided to toss 'im.

I found it on the following Ruby page:

There once was a language named Ruby
That did wondrous things for the newbie;
The programs they made
Would help them get laid
Even though they were nerdy and gooby.

Disclaimers: The respective creators of Perl, Ruby, and Python do not
necessarily know each other or hang out together. We don't necessarily
condone promiscuity or animal neurosurgery or Netware.
Cheers, Roman
