Junior Programmer Removes Unnecessary Code

The Pink Panther chopping down the entire tree trunk instead of just the branch holding the axe - that's junior developers in a nutshell. "I'll just refactor this small function" and suddenly the entire codebase collapses. Nothing says "I improved the code" like deleting 500 lines without understanding why they were there in the first place. The senior devs watching in horror as production goes down because "that legacy code looked messy." Trust me, that "unnecessary" code was probably keeping your authentication system from imploding.
