[it's classtime. one of my students is reading his paper on why we should buy his maraca-made-of-a-sprite-can on ebay.]
boy's paper: "if you buy this maraca, you won't even need heroin to be a rockstar! you'll just need to shake your can a bit."
girl in class: "wait. I don't understand. why do you need girls to be rockstars?"
[if this doesn't make sense to you yet, consider: heroin vs. heroine. yeah.]
