He eats art....

I had to learn Frenchwords and "constater" was one of the words, which didn't want do go in my mind.... constater means to detect sth. So I drew a pun with "const" and "ater" to remember it better :

const --> Kunst (art)
ate --> past from eat (yes it isn't really clever to need an English word to learn French words.....)
er-ending --> er (he) It's a Boy...

So the teacher detects that he eats the art...thing. Whatever it is...
