Well, my favourite (music geek) thing like this to do is to sing "Take Me Out to the Ball Game," but starting the words two notes before the right spot (it starts out mi-re-do-DO-la-sol-mi-sol-re--and the words normally come in at the first do--but start the words from the initial mi instead). So the accents of the words and the music are out of synch all through the whole song, all the cadences are in bizarre places, and the words of the song end two notes before the tune does. It's a great way to drive the people around you nuts, should you happen to want to do that!
