John Cena To Replace Fred Flintstone?

"Wilma must be happy!" might be your first thought when you hear that John Cena would be replacing Fred Flintstone. I mean, what animated lady from the 60's wouldn't want to trade in their Ralph Kramden rip-off of a husband for a 19-time WWE champion? But as it turns out, Cena's just doing a guest run on the front of Fruity Pebbles cereal boxes. It's a shame really. Wilma deserves a champion.
