[em-bee]

a host is a host from coast to coast,

and no-one will talk to a host that's close,

unless the host that isn't close

is busy, hung or dead.

(sing to the melody of the talking horse mr. ed)

i don't know how old this is, and it still fits to the internet, but it's definitely from a time when BBS were still around.

[Stratoscope]

Go right to the host and read the post,

You'll get the answer you love the most,

But all the way you'll never boast,

Talk to BBS!

People yakkity-yak a streak,

And waste your time of day,

But BBS will never speak,

Unless there's something to say!
