Might be a loose interpretation of 'vacation', but I was running a marathon using my phone for tunes, when suddenly I got a call from my boss; our application server had died and he had no idea how to restart it. So while running the race I was timing my exhales to give him the step-by-step instructions for reset-to-restart. The good news is that the miles just flew by as he read the logs, and I responded with commands. Suddenly I was at mile 22 and was actually feeling pretty good; didn't finish the race with a PR but was happy with the result and did get the server back up.
