* FanNickname: On a few sites, the [[http://www.flickr.com/photos/tenpoundhammer/8393725192/ late 2000s]] "Forever Young" building design has gained the nickname "Giant [Yellow] Eyebrow [[DoomyDoomsOfDoom of Doom]]".
** In many places, "Mickey Dees" or "Golden Arches".
** Anybody from NewZealand will know it as "Macca's"
** And in Russia, they're all "[=McDucks=]". Some tried to [[http://prikolps.ru/uploads/posts/2012-02/1329164157_015.jpg cash in on that nickname, even.]]
* ItWillNeverCatchOn: In the BBC documentary ''[[http://www.bbc.co.uk/programmes/b01k6l6lThe Men Who Made Us Fat (part 2)]]'', [=McDonald's=] head Roy Kroc wasn't convinced people would eat larger portions then they were used to and that the Super Sizing idea wouldn't work, or at the very least cause those who had a large lunch to eat less for dinner.
* ScrewedByTheLawyers: [=McDonald's=] frequent heavy-handed attempts to suppress dissent and critical comment. The star example is the "[=McDonalds=] Two" case in Britain, where the full weight of [=McD's=] corporate lawyers was used to attempt to crush two protesters drawing attention to the fast food company's shadier practices. The Two elected to fight back, dragging the case on for five long years, with most of the British and international press supporting the underdog, and every day in court brought more and more bad publicity. The case cost them millions with no realistic chance of recouping the costs from two unemployed activists....
** More recently, [=McDonalds=]' attempt to ensure it was not just the "official" but the ''only'' "restaurant" providing food to staff and ticket-holders in the London Olympics. Their refusal to let the canteen serving Olympic contractors serve chips caused a lot of resentment and unrest.
** Mac Tonight is a more straightforward example. The song in his commercials was basically "Mack the Knife", the English-language version of a song originally written in German by Creator/KurtWeill and Creator/BertoltBrecht, most famously recorded by Music/BobbyDarin (though with rewritten lyrics). This came to an end in 1989 when Darin's son successfully sued for copyright infringement. Mac Tonight wouldn't reappear again until 1997, and again in commercials in Southeast Asia in 2007. As for America? He was turned into an internet meme called "Moon Man", a character created by a user on YTMND who advocates white supremacy, terrorism, and genocide, going as far as to be used in an actual political billboard in the battleground state of Pennsylvania during the 2016 US Presidential election alongside Pepe the Frog (with Pepe depicted as Trump and Moon Man as a Mexican). A few American restaurants still have statues or even functioning animatronics of Mac Tonight, and the character appeared on Jamie [=McMurray's=] NASCAR throwback paint scheme for the 2016 Southern 500.
* WhatCouldHaveBeen: Many attempts to introduce new [=McMenu=] items via "pilot programs" in test markets failed to catch on. If these items '''had''' caught on, [=McDonalds=] might be a different place today.
** As mentioned in the FlawedPrototype entry on the main page, one of these failed attempts involved [=McPizza=].
** In the late 1970s, they attempted to draw in an adult demographic by instituting "The Big Mac Supper Club" -- after 5 PM, they put checkered tablecloths over the plastic tables, dimmed the lights in the dining area somewhat, and played jazz music. When this attempt failed, they tried the same thing again some years later with their "Mac Tonight" campaign. When ''that'' failed, they tried introducing the Arch Deluxe, which was advertised as being revolting to young children (!). To this day, they've never succeeded in attracting the "sophisticated adult dining" audience.
*** The Angus Third Pounder line, introduced in 2009, and the Premium Chicken Sandwich line, introduced in 2006, have a more focused marketing campaign and are more subdued on the whole of their menu. These seemed to be working out until the Anguses were pulled in 2013.
** In 2015, rival Burger King proposed that for World Peace Day, they join forces and make the [=McWhopper=] to promote peace in the world (and raise money for charity). [=McDonald's=] turned them down. BK went on to do it with four other restaurants/fast food places. (Though if one is willing to make the effort, they could make their own [=McWhopper=] by buying them separately and combining them.)
