They Say Things

What's that one figure of speech (or figure of peach, as they say)
for when you are totally starting over?
Going back to square one (or pear one, as they say)?
Yeah, that's it -- square one. Though I'm not sure
why it's a square.
You're right, it seems more like you'd start with
a more organic shape.
Right, like a lump.

Lump one! (or one plum, as they say.)
That sounds kind of dumb.
True, but a square? I mean,
a square is a clean-cut, refined shape,
not like the very beginnings of something.
You're right; it really ought to be
called lump one.
Or at least something like that --
maybe just "the lumps."
Like, "We're going to have to go back
to the lumps?"
We're really at the lumps right now (as they say).
