Bugs Bunny screws around with Red Hot Rider just for something to do in the 1944 cartoon Buckaroo Bugs.
Bugs tells the dullard hero that the Masked Marauder has robbed the 5:15 train (trains always arrive at 5:15 in cartoons). A huge commotion is heard. Cut to Bugs and a huge sound effects contraption.
Lou Lilly is the story man. Manny Gould gets the only animation credit.
