KIRK: So it’s back to the desert for the Minutemen, perhaps for another forty years. Of course, by then, I’ll be seventy years old. A lot of the rest of you will probably be dead. Taylor, you’ll be dead. Babette, Miss Patty . . . that man there in the hat.
From this we learn that Kirk is thirty years old, and born in either 1972 or 1973, depending on whether he has already had his birthday for 2003, or will be turning 31 later in the year. Sean Gunn who plays Kirk was born in 1974.
Kirk’s prediction that many of the older people of Stars Hollow will probably by dead in forty years seems like a slight echo of the story of the Israelites, where an entire generation had to pass away before they could reach the Promised Land.
