Where do tubes come from?

I was always told if you have to ask you'll never know, for what ever that's worth. :)

When a wave rolls over a reef, it pitches out at a faster rate forming a hollow cylinder. I may be wrong here but I don't see how they could come from Russia. So the correct answer is "sea".

they come from Ebay!

Haha Onemug, like totally tubular dude :^)

Here is another one:

THE ADVENTURES OF MICRO-FARAD AND MILLI-AMP
----------------------------------------------------------------------------
---------

One night when his charge was pretty high, Micro-Farad
decided to seek out a cute coil to let him discharge.
He picked up Milli-Amp
and took her for a ride on his Megacycle.

They rode across the Wheatstone Bridge, around
the sine waves, and stopped in the magnetic field by a flowing current.
Micro-Farad, attracted by Milli-Amp's characteristic curves,
soon had her fully charged and excited her resistance to a minimum.
He laid her on the ground potential,
raised her frequency,
and lowered her reluctance.
He pulled out his high voltage probe and inserted it in her socket,
connecting them in parallel and began shortcircuiting her resistance shunt.
Fully excited, Milli-Amp mumbled, "OHM-OHM-OHM."
With his tube operating at a maximum and her field vibrating with his
current flow,
it caused her shunt to overheat,
and Micro-Farad was rapidly discharged and drained off every electron.
They fluxed all night trying various connections and sockets
until his magnet had a soft core and lost all of its field strength.

Afterwards, Milli-Amp tried self-induction and damaged her solenoids.
With his battery fully discharged,
Micro-Farad was unable to excite his field,
so they spent the rest of the night reversing polarity
and blowing each other's fuses.
