I was browsing threads at The Fuselage and came across this neat little game where you can voluneer to push the button.
The game is harder than you’d think. You have to wait the 108 minutes to push the button without entering anything else in. Sure, there are a few eggs built into the program, but it’s really hard to keep from doing something else.
Try entering ‘help’ without the quotes, and you’ll get one of the simpler eggs.  I wouldn’t get carried away with trying stuff out, though, because I’d hate to see the end of the world come any sooner than I already have to.
If you have the time to check it out, press the Execute button at the bottom of the page linked above.
