The moment when I excitedly tell my PM that I was able to replicate our production bug and he looks concerned...

If only!! Spent the last three days trying to reproduce a production bug. Have resorted to checking wind direction to see if that's a factor!!

Although in fairness my boss wants me to reproduce so we can actually resolve it. Or point fingers at appropriate culprits, if necessary.

I've been known to jump up and scream "Yes! It's broken!!" in excitement. It's not hard to find the QA guy in my office.
