LORELAI: Maybe you could do them [the Baked Alaskas] in the actual shape of Alaska.
SOOKIE: Interesting.
LORELAI: Or you could do little baked Alaskas and Hawaiis.
SOOKIE: Because they joined the union last.
It would be very difficult to make Baked Alaska in the shape of Alaska and Hawaii as Alaska has a multitude of islands around its coastline, and Hawaii is a group of islands. I’m sure it can be done, with some artistic licence. Lorelai is joking though.
Alaska was purchased by America from Russia in 1867, and became a US territory in 1912. It was admitted as the 49th state of the US in January 1959.
The Kingdom of Hawaii was overthrown during a coup d’état in 1893, and the country was annexed by the US in 1898, becoming one of its territories. In August 1959 Hawaii was admitted to the union, becoming the 50th state of the US.
Hawaii is the state where Lauren Graham (who plays Lorelai Gilmore) was born, which might be why it is mentioned here. It also happens to be where Keiko Agena (Lane Kim) was born.
