Honestly some of the posts defending "it could be true!!" when nearly any rational reading of it would deem it "fake beyond a reasonable doubt" are just tiresome at this point.
Like you say, it's easy to have a rational discussion that these adverts are dumb and annoying, and purporting this fan fiction as truth just weakens the case.
Not to say ads on fridges aren’t stupid. But they are stupid enough by themselves; they don’t have to make up stories about them.
