Humor and corporations do not much but I always refused to fake the "how interesting, let me add some crap to this bullshit and look as if believe it"
Initially I was the village idiot, and gradually become free to actually say what I want to say. Since it is not really PC it was meet with terrified smiles or dedain. But what was said was said.
I like this situation very much because I can relieve some of the stress and straight lies, without confrontation.
