In one scene the diving board is level with the platform before Bugs spins the diving board 180 degrees. After spinning 180 degrees, the diving board is then above the platform with Bugs hiding underneath the diving board.
At the opening, Bugs as a barker is selling tickets for "fifteen cents", yet a short time later, when he learns that Fearless Freep is a no-show, Sam claims that he "...paid four bits to see a dive..." (four bits is fifty cents). In fact, Sam gave Bugs a wad of bills of unknown quantity and denomination, and so paid much more than either amount mentioned - but for the wad of bills he gave Bugs, he took a large number of tickets.
Bugs Bunny and Yosemite Sam are shown climbing the high dive ladder and they are facing the audience.
In the long shot when they are nearing the top of the ladder they are now facing away from the stage and underneath the diving board..
When Sam is trying to open the door on the diving board and demanding the door be opened, Bugs shakes his head and says, "uh-uh", but his mouth doesn't move.
