Kill her.
I wouldn't recommend it. Buuut, if you do, do it in a fun way. Just don't play any games with her, that's far too generic. Make it fun for yourself and don't give her a fighting chance. Personally I would prefer some form of decapitation, like, knock her out and drag her down to the garage. Make a hole in the garage wall or slip a thin steal cable through a crevice, wrapping one end around her neck and attaching the other to your car or A car. Set up a video camera focusing on the wound up length of cord so she can see how much time separates her neck from the car to where the cable will go taught after it's out of slack. Floor the vehicle gas and wait till the cable snaps tight then loosens. Go back into the garage, and check out the mess. Sure, there will be a lot of cleaning up to do, but at least it was fun and creative. :D
And make sure you hear her crying wimpers before she dies. That's the best part.
