Tony Martin, Cal Wilson, Carl Barron and Stephen Curry give the door a try.

Merrick Watts, Nish ,Bob Franklin and Fifi Box star...

Frank Woodley puts on a vest with a pet-shop logo. Matt Tilley is put in a chemist-like uniform. Ross Noble looks like he stepped through a porthole to another age wearing his leather vest and carrying a staff. And Dr. Julia Zemiro walks through the door wearing blue scrubs and white coat.

Akmal Saleh, Rebel Wilson, Dave Hughes, and Josh Lawson have a go at the door.

Tony Martin is dressed in black with a mysterious scarf. Eddie Ifft comes out in his national uniform, a full cowboy get-up. Julia Morris gets pushed through the door carrying armloads of shopping. And Shaun Micallef looks like quite a dapper gent.

Merrick Watts was looking smooth in a velvet jacket. Kate Langbroek looked peppy; Hamish Blake looked preppy. And Nish looked sharp in a sweater and suit. For the all-in challenge, Kate, Hamish and Merrick looked lovely in their dresses. (That's right... dresses for all three.) And Nish had on a white doctor's coat.

Peter Helliar looked totally groovy in a 70s-style outfit. Stephen Curry was looking flamboyant in a flowered jacket. Cal Wilson said she looked the person her parents were afraid she'd turn into with fishnet stockings and long black dreads. And Josh Lawson looked out of this world in his alien make-up. For the all-group challenge, they took a trip to NASA.
