Continuity mistake: When Bugs sees the finish line, you can see there is nothing on the road and nothing by the finish post. But when Bugs approaches the finish, there is now a line on the road and the post is in front of a tree.
Bugs Bunny: Hey, look, folks! I'm ahead! I'm in the lead! I'm gonna win, yeah! Hooray for the rabbit! Hooray! Look at me go! Look at me go.
