Trudy [on her space friends]

They find it hard to grasp some things that come easy to us,
because they simply don't have our frame of reference.
I show 'em this can of Campbell's tomato soup.
I say,
"This is soup."
Then I show 'em a picture of Andy Warhol's painting
of a can of Campbell's Soup.
I say,
"This is art."

"This is soup."

"And this is art."

Then I shuffle the two behind my back.

Now which is this?

No,
this is soup
and this is art!
