Tangential, but very early in my career, back when I was still using SVN at work, I used to write all my commits in either limerick or haiku, usually smuggling in some curse word(s) with some cheeky message in there. I was convinced that no one actually read them and I could get a laugh out of it.

I did this for months without anyone noticing, and eventually my manager schedules a very awkward meeting asking me why I wrote saying “cfquery fucking blows sometimes”. I had to sheepishly explain that I thought it was funny and then I stopped doing that and my commits became much more utilitarian and much less fun.
