One thing to keep in mind is that the show was shot 2 years ago, so any cultural references that seem out-of-date, like calling Chef Ramsey Jay-Z, should take that into account. The chef with the blue hair is from boston, and he was interviewed in a local magazine. He said he told everyone he was on a trip to Thailand, and says now that it's finally airing, he's having to give back presents friends gave him for his "trip."
