Here’s a fun Stack Overflow thread from last year: What is the best comment in source code you have ever encountered?
It’s eighteen pages of code snippets with amusing comments, ranging from simple warnings like “// Magic. Do not touch.” to cleverly-named objects:
Exception up = new Exception("Something is really wrong."); throw up; //ha ha
It’s a fun read if you’re into programming at all.
The thread has since been locked, so if you have any to add you can post them here.
