Metaphor Jokes

Here's something I got (appropriately) over the net from someone,
who got it from someone, who in turn got it from somebody else. I
have no idea who originally wrote it.
"Think of the Internet as a highway."
There it is again. Some clueless fool talking about the "Information
Superhighway." They don't know didley about the net. It's nothing
like a superhighway. That's a rotten metaphor.
Suppose the metaphor ran in the other direction. Suppose the highways
were like the net...
A highway hundreds of lanes wide. Most with pitfalls for potholes.
Privately operated bridges and overpasses. No highway patrol. A
couple of rent-a-cops on bicycles with broken whistles. 500 member
vigilante posses with nuclear weapons. A minimum of 237 on ramps at
every intersection. No signs. Wanna get to Ensenada? Holler out
the window at a passing truck to ask directions. Ad hoc traffic
laws. Some lanes would vote to make use by a more...

A metaphor is like a simile.
