Failure Friday (May 29, 2015): Did you break something recently? We want to hear about it!

[Previously]

Today's thread is for all the recent explosions, broken parts, vendor headaches, and safety violations at your workplace. If no explosions occurred at your workplace recently, we also accept stories about terrible management and office pranks on the interns.

Guidelines:

• Pictures are very welcome, but please include a story with it.
• Here's an example of a story that might appear in this thread: https://www.reddit.com/r/engineering/comments/1o1qpr/that_day_when_your_boss_almost_dies/
• Share your stories with us, but please do so without revealing your identity or workplace, or violating your security clearance! We assume no responsibility for anything that results from your writing here.
• As usual, moderation in this thread will be relatively non-existent—jokes and light-hearted banter are welcome.
