Race Condition

The classic knock-knock joke format perfectly captures the chaos of race conditions in concurrent programming. In a normal knock-knock joke, you'd expect "Who's there?" to come after "knock knock," but here "race condition" barges in first, completely breaking the sequence. That's exactly what happens when multiple threads access shared resources without proper synchronization—they don't wait their turn, and suddenly your carefully orchestrated code becomes a chaotic mess where operations execute in random order. Your thread says "I'll update this variable second," but surprise! It went first. Now your bank account has -$5000 and you're debugging at 3 AM wondering why mutexes exist.
