What do the letter J and a chicken nugget have in common?

Today Jack asked if he could practice writing his name. I was delighted in this request and got a pad of paper out immediately. We practiced writing the letter J together for a while with very limited success. Then Jack asked if we could turn the page over. I agreed. He then drew what looked like a J to begin with, but ended in a rather odd way. I complimented him and asked, Oh, what letter is that? He then proudly told me that wasn't a letter, that was a chicken nugget! In fairness, it was right before lunch so maybe he was hungry! And objectively, it was a much better chicken nugget than J.
