“‘Down the tubes.’ That’s one you hear a lot. People say, ‘This country is goin’ down the tubes.’ What tubes? Have you seen any tubes? Where are these tubes? And where do they go? And how come there’s more than one tube? It would seem to me for one country all you need is one tube. Does every state have its own tube? One tube is all you need. But a tube that big? Somebody would have seen it by now. Somebody would’ve said, ‘Hey Joey! Lookit this huge farkin’ tube over here!’ You never hear that. You know why? No tubes! We don’t have tube one. We are, sorry to say, tubeless.”

— George Carlin

It seems to me this is particularly funny given Sen. Stevens’ recent comments about how the internet is made up of a bunch of tubes. Not trucks, mind you. Tubes.
