Celebrating Wacky Wednesday the only way they know how, Andy Samberg and his rap trio Lonely Island head to grammar class in their newest video: “Semicolons.” An explainer for the most feared punctuation mark is bold and never-before-charted territory for the rap world. There’s only one problem; they have no idea how to use semicolons. “I’m loud and I’m zipping around; Jet Ski,” is one line. “Always chase the night; young squire,” another. Luckily friend Maya Rudolph sweeps in to save the day at the end. “No actually those are examples of colons, you all get F’s,” she says.
