Hair Trimmed (1953)

Bugs and Sam are fighting each other over Granny. Bugs is a self-declared boy scout, anxious to protect Granny from snake-in-the -grass Sam, who has heard that she has inherited 50 million dollars. It ends with a scene of Yosemite Sam waltzing down the wedding aisle with Bugs Bunny.
