I used to work in local television news production and one of the most common occurrences was something not working, someone calling engineering, and then it starting to work when the engineer walked in the room.
I love these. I would qualify for Arborist and Valued Contributor immediately.
I had a colleague who could have won the "TeeHee" badge. I wanted to tell them about it but they disappeared mysteriously a few years ago and no one seems to know where they went. Especially not Janet, who always has a shovel in their trunk.
(This is sarcasm. I am humorously implying that a person who changes every line of every file in a single commit, breaking everyone else ability to work, disappeared under circumstances implying that their colleague killed them and buried their body in the woods.
I would, of course, never do such a thing. Okay, my alibi is established, let me get my shovel...just kidding.)
