The ultimate parting gift from a developer with a twisted sense of humor! This masterpiece redefines the word "true" to randomly return false 91% of the time. Just imagine the chaos: functions mysteriously failing, unit tests passing on Friday but failing on Monday, and developers questioning their sanity while debugging phantom issues. It's like planting a time bomb that explodes with confusion. The comment "Happy debugging, suckers" is the digital equivalent of a villain's maniacal laugh while exiting the building in slow motion. Revenge served in C preprocessor directives - cold, efficient, and absolutely diabolical.
