Description:  Harvey is invited by Potamus to relax in his new hot tub, wearing a pink shower terry that Potamus has told him to put on. Potamus instructs Harvey to "hit the jets" on the tub and when Harvey does so he is enveloped in a blue light and sucked into the swirling waters of the tub. Potamus follows Harvey, trying to retrieve his hoagie. Harvey and Potamus rematerialize in what appears to be the Stone Age. Harvey attempts to call Peanut (who seems to be hosting a Lamaze class in Potamus' office) but can't get a clear enough signal on his mobile phone. Harvey is caught by a group of neanderthal cave men who believe he's the "pink manbird" (because he's still wearing the shower terry) their oracle had foretold would bring them pestilence and drought. When Potamus appears they mistake him for their pink hippo helmet-wearing God, which Potamus gladly embraces. Phil manages to find out about the portal in the hot tub and brings Peanut, Avenger, and a Star Trek character parody to the past. Phil takes advantage of the limitless resources and lack of economy to start up several business ventures including theme parks and dinosaur hunting. Meanwhile, Harvey serves council to a cave woman who wants to leave her husband for another (exact duplicate-looking) cave man, while Potamus serves as judge. Harvey convinces Potamus not to sacrifice the woman (as the other cave men demand) but to give her and her husband marriage counseling Ð Phil tries to volunteer for it but Harvey decides to do it himself. Phil eventually angers the cave men and Potamus is discovered to be a sham so they all rush back to the watery portal but realize a little too late that the neanderthals and their dinosaurs followed them to the present. They all laugh and the Star Trek parody gets eaten by a T-Rex.
