Today I was working on some regular expression sample code, and remembered this from high school Latin: O Tite tute Tati tibi tanta tyranne tulisti! It's fun to say. Read it out loud. It means "Oh, you tyrant, Titus Tatius, such great troubles you brought upon yourself!"

While I was looking for that, I found malo malo malo malo (which makes more sense than Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo).
