San Francisco CA: A psychiatric conference concerned with why far left wing liberals behave the way they do, was convened at the Mission Bay Conference Center.
The distinguished conference leader Dr. Harpo Marx (no relation to Karl) provided reporters with an overview of the research paper he is to present to the gathering. Dr. Marx indicated the abnormal political behavior of a large number of the residents of San Francisco was studied, including some well known left leaning politicians.
For brevity, I will call these people loons who all exhibit traits of: (1) know-it-all and snooty attitudes; (2) rabid environmentalism; and (3) socialist and anti-Capitalism tendencies. These characteristics are accompanied by a strong desire to spend other people's money.
The prevailing textbook theory is that the loons have no need of toilet facilities, as they are alien mutants. But this theory only explains why the loons exhibit traits (1) and (2). I found that there are indeed toilet facilities in loon's dwellings, which they refuse to use, and that is why they exhibit all three characteristics! In other words "the loons are full of shit."
