During a night of heavy drinking in their hotel room's hot tub, the four douse the console with an illegal Russian energy drink called "Chernobly". The next day, the four go skiing and, after many unexpected occurrences (1980s fashion, music videos on MTV and Michael Jackson still being black), they realize they have traveled back to 1986. Adam, Lou and Nick have also assumed their younger bodies: they appear normal to each other, but to others (and in their reflections) they look like their younger selves. Jacob's appearance has not changed since he was not born yet, though he occasionally flickers.
