What shall I post when I hack my sisters FaceBook account?

[桂英 上官文清]

I have rigged up my tablet to control my computer (shared with my sister) wirelessly.
When she gets back from her holiday and goes on facebook I plan to have my accomplice unplug the the keyboard and mouse (without her knowing) while she helplessly watches us make a hilarious post right in front of her helpless eyes.
MUAHAHAHAHAHA

What should I post?
Bearing in mind that if I anger her she WILL find and scan my naked baby photos that my mother must surely have somewhere

[The Doctor]

Three things to keep in mind:
1. You probably don't care, but if you do that, that's just wrong.
2. She WILL be angry.
3. She WOULD find and scan them.
Ergo, don't do it.
