Bumbling loser and dispenser of the Adapti-tool Cliff drops into the shop in the hope of being able to set up a small booth to distribute his product and Mike, in a surprising moment of amiability, harangues Rex until he submits to Cliff's request. However, after a masterclass in how to sell his product from the effervescent Kenny, Cliff makes the transition from nice-guy-loser to rip-off-merchant in a short space of time, prompting Mike to regret his instant kindness. Meanwhile, Rex and Julie's dispute reaches boiling point.
