Plot summary
Bonnie and Tammy are very happy to start their new joint construction firm PlunkenDorf, but Tammy quickly becomes very uncomfortable with Bonnie's mix of stretching the truth and outright lying to get them jobs. When Tammy can't handle the lies anymore, she tells their first client the truth and he fires them, leading to a major argument between the women and a fracture in the group. Marjorie helps Bonnie see that she does not need to be the dishonest hustler anymore, and Adam tells Tammy that when Bonnie behaves in an objectionable manner, it is usually derived from good motives on her part.
They go back to the client and a combination of honesty and their agreeing to spend time with his annoying mother-in-law gets them back to work. Elsewhere, Jill goes through the ups and downs of cutting sugar out of her diet, finally deciding that the "no sugar=smaller breasts" equation doesn't work for her. Title meaning: An item Bonnie is trying to price for PlunkenDorf, and how Tammy describes scratching her back on a 2x4 upon getting all-over hives when she's stressed about lying.
