That mug speaks nothing but hard truth. Debugging is the perfect crime drama where you frantically search for the villain who broke your code, only to discover it was you all along. The plot twist nobody wanted but everyone deserved.
You start with such confidence, wielding print statements like a detective's flashlight, setting breakpoints like police tape, only to eventually face the horrifying realization that the bug was caused by your own careless typing or logical fallacies from three hours ago.
And the worst part? The relief you feel when you find the culprit is immediately followed by the shame of knowing it was your own handiwork all along. Crime solved... dignity lost.
