BossJoker is a software that hides in the background of your computer, and pops up after a predetermined time with a joke about your boss, teacher, father, bigger brother, or even yourself. For example your boss's name is Mr. Jack your jokes will be like: If you spell Mr. Jack in scrabble you win. Forever Mr. Jack can divide by zero. There are 250 jokes available for you, but if you make a donation of any amount you will be sent a code to increase the number of jokes to 725. The software stays hidden and no one can close it, unless you want to, so you can configure this to run on startup and plant it on a colleague computer, and school computer to unhide the software just press Scroll Lock. Version 1.1 has fixed a bug when selecting high delays and fixed a bug that may happened when saving settings.
