Episode #4823 is great all around, but during the showcases things get absolutely heart-warming. The nervous and excited top winner, a women in her 30s or 40s, keeps herself calm by holding hands with the runner-up, a male college high-jumper. (The camera gets a close-up of this as one of the showcases is in progress) When deciding whether to bid or pass on Showcase 1, she asks the runner-up, "Do you want it?". The runner-up ultimately wins, and he and the top-winner hug each other and then they both hug Bob.
Almost lost in all this is a rare celebrity cameo, the mute clown Emmett Kelly, helping to present a circus showcase.
(Edit: Out of curiosity, I checked Wikipedia, and Emmett Kelly was in fact already dead by the time this episode taped. The man appearing in the showcase may have been his son, who also played Emmett Kelly's clown character, although apparently without his father's blessing, causing the two to become estranged.)
