A thread on comp.lang.python asking about text-to-speech libraries turned into a call for Python limericks. The discussion meandered on for a while (let's just say there's a reason most of these people are engineers rather than poets), until Michael Spencer posted this piece of brilliance:

How about a category for executable limericks?

Here's one to get the ball rolling:

# voice only the alphanumeric tokens

from itertools import repeat
for feet in [3,3,2,2,3]:
     print " ".join("DA-DA-DUM"
     for dummy in [None]
for foot in repeat("metric", feet))

Michael

P.S. I know 'three' doesn't rhyme.

Not only is the Python code itself in the form of a limerick, but if you run it, it prints this:

DA-DA-DUM DA-DA-DUM DA-DA-DUM
DA-DA-DUM DA-DA-DUM DA-DA-DUM
DA-DA-DUM DA-DA-DUM
DA-DA-DUM DA-DA-DUM
DA-DA-DUM DA-DA-DUM DA-DA-DUM

Genius!
