When Jughead starts running around town sporting a bone in his hair and clad in fur-covered shorts, Archie and the gang start to wonder if their prank-prone pal has finally lost his marbles. Turns out that this Neanderthal newcomer isn't Jughead after all, but his prehistoric ancestor. The cryogenically frozen caveman had been preserved in ice for thousands of years, and now thanks to a big thaw he's ready to live it up in a strange new world. After the gang gives this club-wielding time sleeper a hip new makeover, he may even be able to find a date for next week's Homecoming Dance.
