Take your couch and let someone be in the couch under the pillows (or however it is called) in a way you wouldn't notice and tell him to some stupid stuff when someone goes to sit on it, like poking with a stick or so.
However, the person that is going to sit on it knows he's there, so he's going to "jump-sit" on the couch (or something else if anyone knows a better idea). :o
You get the point. ><








Anddddd, maybe a mention in the bottom corner, like MTV/VH1.
