Autograph or graffiti?

The above is what happened to one student’s MacBook during Steve Ballmer’s recent Trevacca Nazarene University visit. It should be noted that the MacBook wasn’t entirely Apple:

…the machine was running Windows—we’ve yet to find out what would happen if Ballmer was asked to sign a MacBook running OS X.

Maybe it would be something like what happened to the second, less-fortunate student who asked for a MacBook signature:

Accident or foul play?

Personally, I would’ve had Ballmer autograph my retail copy of Windows ME—or does the statute of limitations apply?
