Grab some paper, fold yourself a plane and take flight!
If you like this image a wallpaper version is availble here.
Of course your going to need a massive piece of paper unless your the size of a small mouse, in which case any piece of paper will do. (Damn those lucky mice, getting all the breaks.)
Of course don't forget your passport if you plan on flying far away, and if it's a really long journey it's best to pack a little snack. I'm going to take some jelly in the shape of a hedgehog with me (it's much tastier that way).
