Sartre said it better but he was French, not as funny and did not draw cartoons.

The sign in the lower right corner is a great touch. (Please inform the clerk if you are a nitwit. Thank You) My husband's employer should consider posting a sign like that. It would have to be bilingual.

The stories of stupidity does provide my husband with some entertainment and me with cartoon material. It is only funny after the nitwit has left. Dealing with the nitwit can be quite stressful during the encounter.

The second funniest thing behind fart jokes - violent accidental almost killing. My husband can tell which shotgun can cause that much damage to an easy chair.

I've often wondered how one becomes a motivational speaker. I'm not talking about people that have accomplished something in another field then asked to become speakers. I'm talking about people like Anthony Robbins and Brian Tracy. As far as my research has shown neither of these men have achieved success in other fields. They are famous only as motivational speakers/ success gurus. They have achieved success by convincing others that they understand the keys to success and for a price will share the secrets to success. The hard part would be convincing the first person to purchase your material.

Prospect: So you know the keys to success?
Guru: Yes, yes I do!
Prospect: Give me some examples of success that you have achieved using these keys.
Guru: Well, uh, this is my first business and you are my first student but it is all right here in my book, DVDs and Cd's. Everything you need to know in order to succeed.
Prospect: Call me after you have achieved success.

A vulture has to do what a vulture has to do in order to survive.

Clever gag. I wish I thought of it.
