On Weird Al's new album (Poodle Hat) there's a song about the Spiderman movie set to the tune of Billy Joel's Piano Man. It's not as good as some his other songs about films, but I was tickled by:

Now Norman's a billionaire scientist
Who never had time for his son
But then something went screwy
And before you knew he
Was trying to kill everyone

I think "screwy" is just an inherently funny word. Like "kumquat".
