The Masters ponder the perfect meatballs.

John starts prepping his Vietnamese Chicken Meatball.

Floyd hopes he doesn't "meat" his match.

Suvir knows that most of all, he's looking good.

Mary Sue almost makes it look easy.

It just clamps right on the table George, don't look so confused.

The cheftestants wait to hear if their meatballs brought Kelis to the yard.

George thinks the winner of the meatball challenge is at the other end of his finger.

Kelis knows it's crazy that not only is she a pop icon, but an accomplished chef.

Looking fierce yet professional Kelis. We dig.

Nothing says '60s like fondue -- albeit less cheese and more choosing a dish from the pot.

Joan! 'Mad Men'-star Christina Hendricks and her husband Geoffrey Arend want '60s-inspired food that's actually delicious.

Hugh is back, and breaking into a run to ensure he stays.

That basket of lettuce looks quite heavy Celina.

Orange you glad you got Duck a l'Orange, Sue?

The world is literally John's oyster.

George makes some space in the very crowded kitchen.

Traci manages to make it work, even if she's cornered.

Uh oh Mary Sue, is Curtis trying to make you nervous.

Look at that super cute couple. When will Geoffrey and Christina invite us to their cocktail parties?

John and Sue channeled the '60s and lived to tell the tale.

The judges seem to be getting into the swinging '60s' spirit.

Curtis regales the crowd with his Joan impressions. (We wish.)

Digging in.

James Oseland offers a very emphatic hand gesture of praise.

Uh oh, Christina's got some ginger competition.

So much friendlier than Joan.

Celina and Hugh give the chefs the lowdown on their dishes.
