In the fifth segment, Bugs is seen approaching Betsy Ross’ home where she is sewing an American flag (presumably after several failed design attempts, this is the first iteration of the flag - it has the 13 red and white colony stripes and blue field). He says: “Hiya Bets - how’s the flag coming along?” She opens the flag displaying it and asks: “How’s this, Mr. Bunny?” but Bugs makes a comment to Betsy that something is missing in the blue field. (Note the sign at the front gate that says: “Watch your step - Geo. Washington slipped here”[4]). Pacing back and forth thinking hard about what can go in the blue field, Bugs unknowingly steps on a rake and the handle hits him in the head, forming a circle of stars around his head. He then looks at Betsy and asks: “Hey Betsy, does this give you an idea-r?” Betsy agrees, and starts sewing the stars into the blue space on the flag. That is how rabbits helped with the formation of the American flag.
