Uncle Jesse is officially off his rocker. ER star, AND former Full House-r John Stamos made a hilarious appearance on Australian TV show, Mornings with Kerr-Ann, earlier this week AND seemed TO be either drunk, high, suffering from a personality disorder or all of THE above. Check it OUT below -- it gets even better towards THE end: A rep FOR Stamos blames THE crazy on "exhaustion." If by "exhaustion" he means "boatloads OF pills" then I guess yes. Somewhere OUT there, John's ex, Rebecca Romijn, is thanking THE heavens that she took THE "Stamos" off her name.
