The Marines Birthday reminded me of a 7th grade general music class about 15 years ago.
We were finishing a unit on music of the armed forces. We sang the Marines Hymn, etc... I was giving a test:
What are the branches of the United States Military?
Student answer: roots, leaves, trunk, branches, stem.
I thought OK, thats interesting.
Then I got to the next paper. Which had the exact same answer.
