I saw Chuck Berry perform his famous song Maybellene in some '50s Rock n' Roll documentary last night, and it made me think of the makeup company Maybelline. In Chuck Berry's song, he sings: "Oh Maybellene, why can't you be true?" And I thought it might make a fun attack ad for a competitor of the makeup company Maybelline to use this song in an ad that shows someone having their makeup give them problems. Maybe they could smear their lipstick and look silly, or kiss some man who then gets caught by his wife, and then she cries, which makes her mascara run down her face. And they could just repeat the line over and over again while they show this stuff happening: "Oh Maybelline, why can't you be true?" Then, the competing cosmetics company could say that their makeup won't be untrue to you like Maybelline, and their lipstick won't get on anyone's collar, it won't smear, and it won't run down anyone's face even if they cry, which could only be tears of joy, so long as you use (whatever brand of) makeup!
Or, maybe they could suggest that Maybelline makeup is what makes people cheat on their spouses, etc. Or perhaps they could even accuse Maybelline makeup of intentionally getting lipstick on men's collars to bust you when you cheat (or just to get you {and the man} in trouble even if it's just a friend or family member you kissed). And next their ad could show scandal rag headlines about a torrid affair, and all because Maybelline makeup came off onto a man's collar. Then the competing cosmetics company could say that only their makeup protects you from such awful consequences.
And last but not least, a competing cosmetics company could make attack ads making fun of Maybelline's slogan. So an ad could show two snarky models looking at some unattractive woman, and they could say: "Maybe she was born with it." "Maybe it's Maybelline." And that's why you should use (whatever brand of) makeup instead.
