Weird History Food just dropped a meaty new video that might have you rethinking your next cookout. In “Everything That’s Actually In A Hot Dog,” they unwrap the deliciously weird (and sometimes alarming) truth about what’s really inside that bun. Did you know hot dogs were introduced by German immigrants in 19th century New York? Now they’re as American as baseball, apple pie, and questionable life choices. The video takes you through the history, from their humble beginnings to their reign as the kings of ballparks and BBQs. But here’s the kicker: ever wonder what’s really inside them? Turns out, federal law requires them to be at least 54.5% real meat—yep, just over half. As for the rest, well… let’s just say it’s a mystery that might make you switch to… something else entirely!
