"I once went over to my sister's boyfriend's house while I was supposed to be watching his cat.  He's always been a total douche-bag to me, and he doesn't treat my sister very well.  Well anyway, I had the keys of course, and a vendetta...so the day before he was supposed to come back, I had a couple of friends come over to the house, and we completely rearranged his house.  I mean, COMPLETELY!  We didn't mess up any of his stuff, but we took all the furniture and put it in different rooms...like we put his bed in the garage...we put all the kitchen stuff in the bathroom.  The best part was that we did it all nice - like made the bed (in the garage)...put his TV and stuff in the other room but set it up just like it was before, except in different rooms!

Well of course he knew it was me, and it was a lot of work, but it was hilarious watching him come back and try and figure out where all his shit was.  My sister thought it was funny too...

FYI, they are no longer dating  - I think she realized after the prank that i was right about him being a total dickhead."
