sometimes, asking, "what do you see?" can elicit some amazingly insightful responses.
here are some examples i've encountered, while teaching at an art gallery.
and just a reminder, the entries are not my personal commentary on the pieces or art collections, just verbatim retellings of responses i've heard.

"so what do you know about Mao?"
student 1: "that his actions led to the death of thousands of chinese people."
"...okay. what else?"
student 2: "he's not blue."
Mao Portfolio of 10 - Andy Warhol

student: "his mouth looks like a pecan!"
Mask (Gongoli) - Mende
"alright, so great jobs telling me some rules about the art gallery. are there any other question before we start the lesson?"
[student raises her hand]
"yeah, go ahead."
student: "do you have zombies here?"
"hmmmm, not today."

student: "so there are some things in the african art section."
"....like what?"
student: "things that we don't talk about very often."
"i don't understand what you mean."
student: "things like this. like the top part. we don't talk about those things."
"okay..." [walk away]
Female Figure - Kongo
"so what kind of festival could this be?"
student 1: "maybe a celebration of the harvest or new crops?"
"what do you see that makes you say that?"
student 1: "well, they're using leaves and grass and i see a plate of bananas."
"good! so based on what we see in the --"
student 2: "BANANAS!"
"....."
