Technical Details



This dialog has a 'Cancel' button. After that the countdown starts. The 'Cancel' button can't be clicked because it moves away when mouse cursor appears near it. When the counter reaches zero the screen goes blank for a second and then the joke shows a message in big letters 'Just Kidding...'. Shortly after that there appears 'Done' button. After this button is clicked the joke passes control to the system.

The joke is written in Visual Basic.
