Stuff You Should Know's First-ever Crowd-sourced Quiz

This one was posed by @JacobTang2. Sealand, a sovereign nation that appeared in the "How do I start my own country?" episode has the Sealand dollar as its currency. It's pegged to the U.S. dollar in value.

We also would've accepted "octopods." As we learned in the "Octopus, Octopi, Octopod, Octopuses" episode, there are at least three accepted plural forms of the word "octopus." @DisquietTheRiot suggested that question.

Chuck likes to know that only he has breathed on his microphone cover. That question was asked by @Sarijo.

Thanks to @DrOwlPhD for this question. The word "yo-yo" means, "come, come" or "come back," in Tagalog, the native language of the Philippines.

TechStuff's Jonathan Strickland served as co-host for the "How the Necronomicon Works" episode. He also played the voice of Charles Darwin on the "How Earthworms Work" episode. Twitter follower @Duskborne could have told you the answer to this one, since he asked it and all.

The crime fiction author Patricia Cornwell was called "monstrously stupid" by the curator of a British museum for destroying a painting by Walter Sickert in search of proof he was Jack the Ripper. An excellent question posed by @latuacantante17.

As discussed in the poorly named "How Redheads Work" episode, it takes as much as 20 percent more anesthesia to put a redhead under for surgery. Why? Listen to the episode. A fine question by @MissTrust90.

A study investigating decapitation as a humane method of euthanizing lab animals found that electrical activity associated with consciousness in the brains of mice persisted for about four seconds following decapitation. Yow. Thanks to @morthouseblog for that one.

Gluten leaves the body fairly quickly when it's cut from the diet, so if you stop eating gluten, a gluten allergy won't be detected by your doctor and a false negative will be found during allergy testing. That one's from @MorganFryPasic.

Something of a trick question since Chuck was never a smoker. Josh, however, smoked for 20 years before he quit. Thanks to @Max_Bobbitt for that one.

In the "How Thoroughbreds Work" episode, Josh and Chuck mention that horses born in the Northern hemisphere all have the same birthday, January 1. Southern thoroughbreds all share the birthday of August 1. The shared birthday keeps things simple, supposedly. Good one, @hmluker.

In the "How Shrunken Heads Work" episode, Chuck and Josh discuss the Shuar, the only indigenous group known to shrink heads. Thanks to @KieraJo for that one.

As heard in the "Tone Deafness" episode, Bing Crosby, Jimi Hendrix and Yanni all have perfect pitch. Man, that was a good one. Thanks to @skittermax.

It was Nikola Tesla's alternating current, installed by the Westinghouse Company, that lit the World's Fair in Chicago. It was the culmination of the "War of the Currents" between Tesla's alternating currrent (AC) and Thomas Edison's direct current (DC), as described in the "How did Nikola Tesla change the way we use energy?" episode. Thanks to @jrwyke for that one.

Red Sox great Ted Williams, a.k.a. "Teddy Ballgame," was placed in cryonic suspension upon his death in 2002. His body and head are both in cold storage in Arizona. Great question from @ponypandaturtle.

While it's entirely possible a Hells Angel or two has lent a hand to the other NGOs listed, Toys for Tots was the only one of these three that Chuck and Josh mentioned in the "How the Hells Angels Work" episode. A fine question posed by @zeHobocop.

The duo over at @twoshedsband know. Josh opts for a battle axe in the event of a zombie apocalypse. Chuck goes for crossbow with exploding arrow tips. Chuck lives.

In addition to the endogeic earthworms that dwell just beneath the soil surface and the epigeic ones that live above ground beneath leaf litter, the anecic -- the deepest dwelling of earthworm types -- form the three types of earthworms. Thanks to @mingle for the question.

The role of Winston was originally created for Eddie Murphy. Thankfully, Ernie Hudson stepped in and filled the role. Chuck and Josh can't even begin to remember which episode they mentioned this in, since they talk about "Ghostbusters" in a lot of them. Probably @abigflea could tell you since he asked the question.

By 2006, LEGO had built an estimated 4 billion mini-figures. They're clearly poised to take over the world. Thanks to @JoeRubiks for coming up with that one.
