Whenever I'm leaving a job, I keep a look-out for opportunities to change lines that rarely change. Things like doctype declarations, blank lines, closing braces, stuff like that. If I can change them, my name is memorialized longer in the `git blame` of projects.

People will find ways to gamify everything. It's quite often a release valve for stress or boredom.
