Being run it imitates Windows having fatal errors by opening series of messageboxes with error messages. After that another messagebox appears with the text:
Are you sure you want to format the hard drive ?
There's only 'OK' button in this messagebox, so the user has to press it anyway. Then the joke opens another dialog with hard disk format progress indicator and the text:
Formatting hard disk. Push Escape to cancel.
If you press 'Cancel' button there appears a messagebox with the text: "Necessary files not found!". After that or when progress indicator reaches 100%, the screen is filled with garbage and the joke waits for keypress. Then the final messagebox appears with the following text:
I scared you, didn't I ?
English and German versions of this joke exists.
