Funny thing I saw the other day!

At the top of a particularly convoluted and otherwise completely uncommented code:

// Abandon all hope, ye who enter here.

And in some PHP code for a webpage I was hired to work on:

// Since this file is loaded on every page, and since 
  // I want the following function on every page, I'm going to 
  // cheat and include it here even though it has nothing to 
  // do with the other things in this file. 
  // If you don't like it, bite me!

Gotta love coders!!!
