Sack of what?

In Washington State History, my students are hard at work (or hardly working depending on the kid) on their explorer biography project. Today's assignment was to show me their rough draft since it's due tomorrow. As I was checking I came upon my student who might possibly be the world's worst speller. Even knowing this, I found it absolutely impossible not to laugh at what was written on his paper. In an effort to spell Sacajawea, he wrote the following:

Sack-of-jewea

I kid you not this was what was on his paper. I started laughing, he started passing his paper around to show his friends so I wrote his spelling up on the board so we could all enjoy it together. It was a good thing.
