How to remember information by Jason

So we're writing notes in Neurotreatment class today and at some point and time we all pause because on the board it says:
"Dramatic weight loss elephant"
Ok so you see we're not talking about elephants but rather about Huntingtons Chroea (which has nothing to do with elephants). So we asked our teacher why it said elephant on the board and he says:
"Because I am putting random words on the board so you can remember the information later on."
We all had a good laugh.
