It’s a bird! It’s a plane! It’s… an ad for cigarettes?! For the past 102 years, people have been using airplanes to turn exhaust into ads, political slogans, birthday greetings, and more. But where did this strangely brilliant idea come from? What kind of sorcery do pilots use to make it happen? And why is it at risk of becoming a lost art?

This week Will and Mango celebrate their own wonderful grandmas by paying tribute to a whole world of awesome grandmothers. From a cuddly graffiti gang in Europe, to a group of grandmas who advanced our understanding of marine science, to a few celebrities who never would have gotten where they were if it weren't for their Mamaws, here's to all the grandmothers and grandmother-figures we're so lucky to have in our lives.

Today’s an important day in Holmes history, so Mango is joined by Part-Time Genius super producer/Sherlockian Mary to explore some lesser-known facts about the greatest detective ever written. Grab a magnifying glass and your deerstalker, and discover the weird connection between Sherlock and Popeye, the real-life man who may have inspired Professor Moriarty, and the unsolved mystery of the first Sherlock Holmes movie!

Yes-- that's a photo of Mangesh as a 3rd grader the first of two years in a row that he went as Sherlock Holmes for Halloween.

If you’re anything like Will and Mango, you remember playing with Transformers as a kid. Or maybe you still enjoy transforming bots, in which case you should know the correct verb is “converting.” On today’s episode, we take a closer look at this ubiquitous toy with a surprising history that includes tea-serving dolls, WWII scrap metal, and a strangely touching example of corporate collaboration.

Here’s another fun fact: we’re on Instagram! Find us @parttimegenius, and feel free to leave comments or questions for the show.

Look, we love Lady Liberty as much as the next patriot. But why on Earth did France give America a massive and exoribitant gift that wasn't on our registry? Will and Mango dig into the bizarre Parisian dinner party that led to the idea, the mathematical word problem of a way the statue was built, why it competed with a walrus for early tourists' attention, and why Brigham Young, Ulysses S. Grant and Gustave Eiffel from Eiffel Tower fame all have more to do with it than you'd think!

Everyone knows the painting "A Friend in Need" aka Dogs Playing Poker. But did you know the artist behind it started a bank? And had patents? And also once got an apology from Far Side creator Gary Larson? We didn't either! Tune in as Will and Mango discuss the most important painting about whiskey-drinking dogs playing cards and also visibly cheating while doing those two other ridiculous things.

Need a reason to be optimistic about democracy? Will and Mango welcome best-selling author A.J. Jacobs to chat about his new book The Year of Living Constitutionally. From walking around the upper West Side with a musket (a 2nd amendment right!), to delivering quill-written petitions to Congress (he spilled a lot of ink in the process), to meeting the last person to get a new amendment added (all the guy wanted was a better grade in his college class!), A.J. discusses his sweet and ridiculous experiments in patriotism, and how it helped him gain new insight into America's founding documents.
