Explosive Shack on the Tracks

While Wile E. is preparing his final plan to catch Bugs using carrots filled with nitroglycerin, the rabbit in question moves his explosives shack into the middle of the railroad tracks. The coyote is so busy bragging to himself about being a "super genius" that he doesn't realize what's happening until he looks out the window and sees a train coming right at him.
