by Jeannie. As Merle attaches his picture on the wall of shame, his prompted to add a dab of paint to his picture to denote where he had cut himself. His extra lesson is a long lecture about what is safe and what isn't when it comes to cutting, of all else, duct tape. The episode begins with Merle showing up early and completely disassembling his duct tape-patched drywall from the first episode, due to his inability to sand and apply a second coat of plaster (which was done during the events of an earlier episode). At first, he opted to chisel off the plaster (instead of sanding) and sealing off the second coat with newspaper, but the ceiling had apparently haunted him enough to do the drywall path over again. This time around, Merle does the drywall patching correctly, complete with a shim for support, all without duct tape, which he vowed to avoid for the remainder of the day. As the rest of the contestants file in, they are told to do a final coat of plaster on their drywall patches.

Merle quickly caves (while the others, especially Keith, aware that the stipulation was a joke at Merle's expense, refuse) and begins the challenge with duct tape. Darryl – Darryl had minor problems with his stapler. However, when reassembling the stool, some of the screws were still loose. Merle – Merle chooses to upholster his chair with duct tape (while the rest use fabric), believing that it will get his job done faster (it certainly doesn't get the job done safer). He is also the only one to use a utility knife to cut his duct tape, while the rest use scissors to cut their fabric. When Andrew insists that duct tape is not meant for upholstering, Merle does not budge, having already completed half his chair with duct tape. However, Merle is forced to stop altogether when he cuts himself using
