The Bathroom Protocol: Mutex vs Semaphore

The bathroom analogy for concurrency primitives is both disturbing and perfect. When you're learning about thread synchronization, no textbook explains it this clearly. Just imagine a senior dev dropping this knowledge bomb during standup while maintaining eye contact. Now you'll never forget the difference - mutex locks the whole bathroom while semaphores let a fixed number of threads do their business simultaneously. Bet your CS professor never made it this memorable.
