So lets look at these people.

Clarks:

David Hyde Pierce (TV and some movies)  

Diane Keaton (actress movies)

(the clothes, right down to the shoes/boots. she talks about everyone else)

Woody Allen (comedian film maker)

Jimi Hendrix (musician)

The first thing you might say, ‘wait a minute, not a introvert, look at the stage prescence’. Look at the interview, clarks will be as abstract as can be, they are also the truely creative ones ( of the three).

Prince (musician)

 (If you had never seen Prince before and saw this interview first, I doubt if you would believe the difference.)

Bob Newhart(comedian and actor)

Richard Linklater (director and writer)

 Starting with Slacker, his movies speak to the clarklike view of the world.

Uma Thurman(actress)

 The posture, the clothing, the way of relating to the world, this is a clark.

Flo (Progressive Insurance actress)

 (the shoes, watch for the shoes. also excessive hand motion)

Steven Wright(comedian)
