Very very old joke: So Josef and Abrasha are talking and Abrasha says, this new radio thing, I don’t understand how it works. Well, says, Josef, you know how a telegraph works? Abrasha: No. Josef says, I’ll explain: Suppose you’re in Minsk and I’m in Pinsk and I want to tell you something by telegraph; well, imagine a very long dachshund with its tail in Pinsk and its mouth in Minsk. I pull on its tail in Pinsk and it barks in Minsk. Understand? Yes. That’s how a telegraph works. Fine, but how does radio work? It’s just like a telegraph but without the dachshund.
