Tree Topper

I'm in charge of putting up the biggest Christmas tree ever, but there's just one problem, no one put up the tree topper before the light ceremony. And if you want something done right you have to do it yourself. Our science department has an idea, they have a growth ray and a plan. They shoot me with the growth ray and I grow and grow and grow until I'm towering over everything and can place the tree topper on myself.
