I don't mean like scams or anything like that. I mean what's the ad that has done the worst job as an advertisement? Instead of making you want to buy the product you wanted to avoid it.
there was an old ad with a kid sitting on a dock fishing, eating a bologna sandwich and singing "my bologna has a first name, its o-s-c-a-r. my bologna has a second name its m-a-y-e-r"...
nothing wrong with the commercial except it turned out to be an ear worm that would live in my head FOREVER. my brain trots it out at least once a month for no good reason. usually more.
ive never bought bologna and i'm low key mad at Oscar Mayer so maybe this counts?
