How Did You Know? - {day 1}

It's an all-new 5-day trivia hunt,
with an all-new set of puzzles, prizes, and collaborators!

Second, the collaborators: meet Josh Halbur, the brilliant mind behind many of this month's puzzles. Currently attending college to become a math teacher, Josh says he only seems to enjoy things that have two Zs, as evidenced by his love of logic puzzles, trivia quizzes, jazz singing, and pizzas with mozzarella cheese. (Take that, Mr. Dogg.) He's also working on a puzzle book, which he hopes to publish before his procrastinating soul dies.

Next, meet Sister Salad, who were inspired by mental_floss contributors, the original nerdfighters, John and Hank Green and their Vlogbrothers posts, and went and created their own Vlogsisters version over on YouTube.

I've cajoled the Salad Sisters (after stalking them) into introducing the first challenge each day this week. So without further cyber-ado, here is part one of today's fairly easy, three-part challenge. Once you've watched the vid, click below to move on to level two!
