Light Saber > Pink Highlighter

Good morning,
"May the twenty first be with you" doesn't have the same ring to it, does it?

When I was little - as in the first time I saw Star Wars - I totally thought they were called "light savers". I was on board with green energy way before it became cool. Although, it didn't make sense that they were "saving" light, because aren't they made of light? My feeble young mind didn't process this logic until later on when my brothers kindly pointed out (read: were totally mean about it and laughed in my face until I died) that it was, in fact, pronounced "light saber".
