A bricklayer lays
another layer of bricks
[Yes, yes, I know,
bricklayers "place" bricks in "courses."
"Bare" with me here.]
For who ventures into your lair
is fixing to get lain.”
and people (or Spiders) lie down by themselves."
Lie: to put oneself in a position of rest
Liar: one who utters falsehoods to get laid
The moral of the story (now we're getting somewhere)
Beware liars lying to lure lovely lovers
to lie with them, and in their lairs, lay in layers.
