Metaphor

I have one beautiful, lovely, gorgeous step:

 metaphors and aphorisms abound

Bob was trying out the durability of the construction adhesive on one stair tread/riser combination before he did the whole flight of stairs.  But it's the most pertyist step you ever did see!

Stairs.  Well, stair.  But soon: stairs.

The End.
