How no 1 son sees himself

Art exhibition at no 1 son's school, and this is one of the AS level exam pieces he submitted. I had to ask about St John's College, but it turns out to be a reference to where he did some work experience last year shadowing the sound engineer on a film recording on location at St John's college Cambridge. I wouldn't have got it, and I was there!

Overheard conversation between No 1 son and one of his school mates, looking at this painting:
Friend: It reminds me of a Warhol.
No 1 son: What is a war hole?
I despair, sometimes. To me it's more Gilbert and George, gone solo.
