Mathletes probably know that March 14 is celebrated as "Pi Day," because 3/14 is a natural time to salute the decimal approximation of pi, 3.14. But if you're a science nerd who's more into biology than physics, you'll be happy to know that March 14 is also National Save a Spider Day in the United States. March is the perfect month to thank our arachnid friends for all they do for us—especially because they're so often misunderstood. Here, let's allow Jeopardy!'s Ken Jennings to smooth out the tangled web of spider myths that might have you deceived.
The Debunker: Do You Swallow Eight Spiders Every Year While You Sleep?
I mean, I guess you could, but you'd have to really want it. They're not going to just wander into your mouth. As University of Washington arachnid expert Rod Crawford says on his museum's website, "No such case is on formal record anywhere in scientific and medical literature," despite people having slept and watched each other sleep for millennia. He points out that this is an urban legend that goes back decades, with a wide variety of phony "statistics" on offer. Sometimes it's a mere four spiders snacked on per year; other times it's given as a full pound eaten in a lifetime.
