When Lucky is commanded to dance in Act 1, Pozzo reveals that he calls his dance "The Net":

The Scapegoat's Agony.
The Hard Stool.
The Net. He thinks he's entangled in a net. (1.589-92)
You would think a guy tied up on a rope leash would feel confined enough. Of course, the image of Lucky writhing in an imaginary net is a lasting image for the play as a whole, and especially for the plight of Vladimir and Estragon, who, as we’ve said before, are confined in a prison—or perhaps a net —of their own imaginations.
