When Dean brings back snow cones for Rory and Clara at the carnival, he mentions they were only cherry flavored ones left, and the color of the snow cones are bright red.

When Rory and Jess walk into the diner and pause, Lorelai can be seen thru the blinds waiting outside for her cue to enter.
Marion Ross's name appears in the opening credits as Marion Rodd.
