Get pregnant and take her on Maury. The damn test is ALWAYS negative. They rig it, I swear, just to keep the hoes comin back.
Look for one of those long lists of stupid things to do during sex. Like the houdini, for example. Try some of those out.
Video tape her and post it on the internet
Get her really horny and then leave her with a toothbrush or something stupid for her to get off with. She'll be mad pissed and will probably use it.
Siegfried & Roy
Get her naked in her house and figure out a way to make her parents see. Videotape the reaction.
Tie her up, tell her you like it. Then leave her there.
There's so many things to do...
