You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat.

I also got a spam message today from an address @portlandhottub.com. While I assume that domain is owned by someone who sells hot tubs in Portland, the first thing that came to mind was every person in Portland, OR lounging in a very large hot tub. Now that would be my kind of city.
