What is the most flagrant example of conceited "bullshit" you've ever encountered?

Today I stumbled upon a pdf of Peter Arnell's redesign of the Pepsi logo, touted by a person on twitter as "the height of human bullshit". And it reminded me of the time I worked at a small start-up company, where these kinds of overblown but substantially empty ideas were common currency.

So I'm wondering: do any of you have any funny or interesting stories of encounters with these kinds of things.
