When the whirlpool in Potamus' office sucks them back into pre-history, Harvey, Potamus, Peanut and Phil must find their way back to the office. Or rather, Harvey needs to find his way back, as the rest want to stay.
Harvey is wearing a pink spa terry during the entire episode, including the scenes in court, the wedding, and back in the future. During the past, Harvey is only once not wearing the spa terry, and that is for the marriage counselling montage. Afterwards, Harvey is again wearing the spa terry.
