I modified some c code about 2 years ago, the code name for that project was ASSCU (sounds like ass cool, don't laugh, it is real, and it stands for "A-Series Source Catch Up"). To indicate the purpose of the change, I wrapped my modifications between this set of comments:

/* ASSCU begin, Peter */
...
/* ASSCU end, Peter */

Recently a guy, did some more change to the same .c file for a different project, he copy and pasted some of my code including comments, but made some smart move and changed my name to his name, so all his changes are wrapped between:

/* ASSCU begin, Tom */
...
/* ASSCU end, Tom */

During code review, I asked the guy what ASSCU means, and why he put it everywhere. He said that he didn't know, he saw it in my modification, and he just thought it was a company standard to wrap all changes between ASSCU. Everybody in the room laughed, and I told him that that was an old project completed 2 years ago. No more ASSCU.
