Analyze our personalities

I think you will have fun if you analyze our personalities based on the following pictures taken at "Top of the Rock"!
The first one is of us sitting on a steel girder "above New York's skyline".  We are OK so far.

 Then we were instructed to "act like you are falling".  Hmm, which one of us rather "ho-hum" about it all? 

 

Finally, I was told to act like I was pushing him off.  I did it.  But look at Spencer's reaction (or should I say "non-reaction"?  Does he look bored with the whole process to you?

I'd say this is a great photo-op describing a lot about our personalities or outlook on life?  What do you think?
