Knock Knock, Who's Thread?

A classic joke structure derailed by concurrent programming nightmares. The "race condition" punchline is pure gold because it demonstrates exactly what happens in multi-threaded code when two processes compete for the same resource without proper synchronization. The joke's timing gets completely mangled - just like your carefully crafted code in production when race conditions strike. And then "Ray" shows up uninvited, like that random value that somehow got assigned when you weren't looking. Your debugging session starts now.
