I love it when rather than fix the bug that is causing the faulty data you write a bot on a schedule to clean up the faulty data. It's like a bot battle who can mess up / clean up the data the fastest. Unless your clean up bot has a bug then you are just F'ed.

I love it when your team lead complains that you aren't getting through your tickets fast enough, but then you are blocked because his super fragile integration tests are on the fritz and the build is broken for days. Sure I could fly through my tickets if I didn't have to fix everyone else's shiz along the way!
