1919 History Riddle

Alright, listen up, you big dummy! Explain bear is here to teach you a thing or two. You know that old riddle, "What's black and white and read all over?" The answer is usually a newspaper, 'cause it's black print on white paper, and you 'read' it. Get it? But this joke, oh boy, this one goes deep for your tiny brain. "Red all over" isn't about reading here, it's a pun, you dunce! It means the color red, like blood and communism. In 1919, the U.S. had a bunch of racial riots (that's the "black and white" part, referring to people and conflict) and also the "Red Scare," which was a big panic about communism. So, it was literally "red all over" from all the violence and the fear of communists. You probably didn't know any of that, did you?
