(it is revealed here that the contestants had also attempted a glass block challenge earlier, although no mention of the challenge itself had aired in previous episodes and that Darryl had performed poorly). Unable to form a plan on the glass block, Darryl returns to the cabinet doors. He manages to hang two, but they do not close together. At the same time, Merle, still in the bathroom, decides to go back to the plumbing as the tiling lay there incomplete, yet the pedestal has not been secured in place, forcing Merle to believe that the sink is drooping is because of an improper bracket installation. He screws a pine board into the wall in an attempt to fix this and gets the help of Keith to handle securing the pedestal and hooking up the pipes while Merle gets the sink in position. Meanwhile, Barry and Jeannie continue their work on the floor, still using very little glue and still taking three times longer than it should. After five hours of work (the halfway mark), no tasks have been completed and Jeannie is believing that everyone's on the right track (even though none of the bedroom tasks have started; as Barry notes, Jeannie's claim that everyone was halfway through was "irrelevant"). Keith and Darryl, still not having adjusted the doors, have moved on to Keith's original task of building the furniture. However, Keith's TV stand (consisting of three boards screwed to each other at this point) had the same structural integrity as the Presbyterian Chair Keith made in Episode 3 that led to him being named the most improved. Keith and Darryl expand upon that structure, although they do little to improve the piece's structural integrity. However, they can now claim that one task is complete. Merle contributes his share of the work when his plumbing is complete and his sink is tested and shown not to leak. The simple parts of his tiling is also complete, although he refuses to attempt the difficult areas (where cut tiles are necessary). This means that with 4 1/2 hours to go (just over the halfway mark), only three tasks are completed. As Keith takes his 15th break of the day, Merle begins to work on the glass block by first constructing a window frame for the port, while Barry and Jeannie continue to lay down hardwood with slothlike intensity.
