How do I break up my sister and her boyfriend?

[Foolishgoldfish178]

In my opinion that's very mean .. but if you really want my advice ..

Every time he comes over , embarrass your sister, ask him questions ,
"Did you guys have sex yet ?"
"Are you thinking about doing oral yet ?"
"You better be using condoms!"
Scream : "Mom ! There doing dirty stuff over here !"
Show your sister what a penis looks like (right in front of him) and gross her out with weird pictures of people having sex .
Hack her facebook account and change her relationship to single - and send him a letter saying im breaking up with you
Tell your sister you saw him kissing a guy .
Try to scare him away with the dirtiest things you can thing of!
