EMILY: We have not been waiting forever.
LORELAI: Forever. Godot was just here. He said ‘I ain’t waiting for Richard,’ grabbed a roll, and left. It’s been forever.
A reference to Waiting for Godot, a play by Irish playwright Samuel Beckett, originally written in French in 1948-49 (title: En attendant Godot). The French play had its premiere in Paris in 1953, and Beckett’s English translation of his own play premiered in London in 1955.
In the play two characters named Vladimir and Estragon engage in a number of discussions and encounters while they wait for the Godot of the title, who never turns up. It has been voted the most significant English language play of the 20th century.
