Adam: Bird nest soup.
Mac: Bird nest soup?
Adam: Yeah, it's a Chinese soup that costs 100 bucks a bowl. You want to know why?
Jo: Because it's made with the rare nest of the Chinese cave swallow.
Adam: And do you know how they make their nests?
Adam: Bird spit. Yeah, when the saliva dries, the nests are imported for like $2,000 a kilo.
