These go under 'missing or modified letters', and are in Swedish. They're both fairly well known from my generation.

The first is from a national bank, nowadays known as Swedbank, but once upon a time called "Föreningssparbanken". Essentiall, the "United Savings Bank" or similar, about 300-some rural banks all getting together under one umbrella. Anyway, some smart person realised that you could modify the above into "Oren I Baken". Which translates into, more or less, "Unwashed Ass". There is a lovely name for you.

The second is from a company that, now, is called "Coop". Which also show what it is. Before they became all international-type-named and hip, with it and cool, they were known as "Konsum", short for "Konsument", which of course means consumer. Essentially, a co-op. And they ran a ad campaign that said, "Kom med i det glada Konsumgänget". Join the happy co-op crew. Peppy, happy, yay. Until someone added the 'umlaut' over the on. "Kom med i det glada Könsumgänget." "Kön" means gender, as well as sexual organ. Join the happy 'sex-havers'....

And then, while it isn't a sign as SUCH, another infamous one in Sweden. There's a real estate management company, primarily in hospitals, in Stockholm, called 'locum', specifically with the lower-case 'L'. A number of years ago, they decided to run an ad campaign showing what wonderful people they were, after all, hospitals are good things. So, they wanted to do a love and happiness thing. And for some reason, known only to the gods, no-one at the company, OR the advertising agency, reacted when they replaced the 'o' with a heart. Cute and sweet.

Yep, that's right: I heart cum.
