Paula Deen -- Family Catches Sugar High for the Holidays

It's not clear what the hell is happening in this Paula Deen Christmas promo ... but one thing is for sure ... she and the fam are happy as butter-soaked clams.

Deen put out this video of her clan whipping up some holiday recipes -- but mostly it looks like they're just getting loopy on carbs and bourbon. Somehow this is supposed to be a promo for the online Paula Deen Network.

Watch as Deen cackles and spews one gem after another -- while her sons parade around like Southern gentlemen. Think "A Christmas Carol" meets "Gone with the Wind."

Weird.
