   Right triangle: "The ratio between my height and my hypotenuse is the
   sine of my angle!"
    Small blob: "The sine of your angle?  Is that important?"
    Right triangle: "I am told it is!  I am very special because my ratio
   is the sine of my lower angle!"
    Small blob, to sine of angle: "What makes you so special, abstract
   relation with a label?"
    Sine of Angle: "I describe how rotation and vertical translation go
   together!  You'll need me if you ever want to simulate a bicycle to
   calculate the ideal height of its seat!"
    Small blob, to right triangle: "Why would I ever want to simulate a
   bicycle?"
    Right Triangle: "Sorry, is this about vertical things, horizontal
   things, diagonal things, or angular things?"
    Small blob: "Umm ... I think is vertical and angular."
    Right Triangle: "Perhaps the arcsine is your answer.  Bicycles sound
   kind of old, and so it the arcsine.  If you ever want to know an angle
   based on a height, the arcsine is your friend!"
    Small blob: "But why would I ever want to know that?"
    Arcsine: "Your angle is indeterminate.  Are you sure you're a real
   number?"
    Small blob sat a little.
   Different small blob: "Trigonometry sure is silly, isn't it, small
   blob?"
    Small blob: "Why are things trigonometric instead of something that
   makes sense?"
    Different small blob: "I think Karl tries to do trigonometry to relax
   sometimes."
    Small blob: "Ohhh! Maybe I can help him!"
    Small blob to right triangle: "One moment, friend trigonometry."
    Small blob to different small blob: "Are you sure he's not trying to
   tell a story?  Isn't this a post to the internet?"
    Different small blob: "Ummmmmmmmmmm.  Let's tell an old mind control
   story."
