Foster's Brewing Group, Bricklayer
A man at an exotic bar -- there are lots of women wearing feather headdresses -- shares a glance with an attractive woman who has sparkles on her face. He asks her if she fancies a drink later and she agrees.
The meet outside under fireworks. She smiles and opens up her silver outfit, revealing a hairy man's chest. His smile falls momentarily and then he shrugs and simply says, "That's great" as he takes a drink of his lager. Apparently a bricklayer who was just on break, he then adds, "You can give us a hand with this wall."
In the closing image, "she" is shirtless and lifts huge cinder blocks and hands them to him.
A neutral though rather bizarre ending to the old "surprise, she's a man" joke.
