Popeye-Parlez Vous Woo (1956)

Olive is so captived by "The International", a radio personality with a French accent, that she'd rather stay home than go out on a date with Popeye. Bluto, overhearing this, comes to the door as the character. Popeye does his best to get Olive back, to no avail. Finally, Bluto challenges Popeye to a duel, ultimately stabbing him in the chest where his can of spinach was. Popeye unmasks Bluto, then eats another can of spinach to give himself a French accent.
