Hall of Fame

PHILADELPHIA—A voting panel of journalists and prominent sports figures elected the D battery to the Philadelphia Sports Hall of Fame Sunday, honoring the alkaline storage cell’s many achievements in pelting players from visiting teams. “The D battery is as synonymous with Philadelphia sports as intoxicated fistfights, cheering for a severely injured player, or intentionally vomiting on a child,” said Philadelphia sportswriter Ray Didinger, adding that the Hall of Fame plans to install an interactive exhibit that allows children to throw batteries at life-size cutouts of rival athletes. . .

Nothing but trouble

The engineer comes in to talk to his chief engineer. "I'm having trouble with that power supply circuit you put me to work on."
"OK, let's talk about it, said his boss. Is it oscillating?
"No," said the engineer, it is stable."
"How is the efficiency?"
"About 87%"
"Is there ringing on the gate?"
"Nothing above normal."
"What about noise and ripple?"
"They are well within spec."
"Then what's the problem?"
"The darn thing's on fire!"

Ed. note: All the puns that are fit to print in one story. Resist trying to read it to your co-workers, serious bodily harm could result.

Reward Offered:

A reward of four bits is offered for data leading to the lightning arrest of this desperate criminal: Hop-a-long Capacity.

This unrectified criminal dissipated (discharged himself) from a Western prism where he was held in soliton confinement in a primary cell, clamped in ions awaiting the quartz decision between the gauss chamber or death by lethal induction. He tunneled through the schottky barrier and punched-through an insulated gate, thus avoiding the mesa's guard ring. Waving Debye, he then beta swift retreat in a stolon standard model alpha. His last meal was to have been erg and pawn curie .

He was charged with the interference, impedance and induction of an 18 turn air-core bobbin, n-sine Millie Henry who was found choked, gapped and robbed of valuable joules, which really erged her and caused her brother Mike O. Henry to re-coil concerned that she had lost phase "Watt a WIMP, I'll barium" he vowed. Though still fit for continuous duty the attendants opted to carrier away on a liter (her CO2 had centiliter). She exhibited reluctance to being shunted away like an invalid, crying "Mind your own bismuth, I'm not dyne" Though later she emitted "It really Hertz." After Huygen her tight, Capacity had even stooped to peltier with rocks.

Hop-a-long, who said he couldn't resistor, is armed with a carbon rod heater, has high mobility and is a potential killer. He wanted Abelian to set her free.

The cholesteric Capacity is also charged with arsenide, and driving a dc motor open-loop over a Wheatstone bridge and refusing to let a band-pass, crushing their mascot woofer beneath a rolling average. Use cation if encountered, he has the capacitance to offer series resistance. If beta captured tie with a phase lock loop, conduct him to the nearest secondary cell and telluride to transmitter wire to the police.

The detectorSherlock Ohms and the localized force, officers Newton and Slug, were catalyzed by the gravity of his crimes and spent the night probing for him in a magnetic field, where he had gone to earth near the symmetry. They report nothing positive and believe he has returned ohm via an unintended ground loop path. They are anxious to run him to ground so he can be passivated and recharged with nu crimes. Please contact them with feedback no matter watt-hour, especially if you hear shot noise.

A native of PN Junction, Hop-a-long will often on a faraday ride a cyclotron (aCarnot cycle) or rho an arc with his short girl friend Eddie Current who plays a harmonic. He drives with a heavy photon the accelerator, making him a super collider. He may flyback to his ohm town where he sometimes Gibbs free energy in the Lorentz district.

"I was a hard-working clerk making $30,000 per year. I was frugal, living carefully, saving my money, and I was happy and content.
Then one day I fell in with some shady characters and I got suckered into a high-stakes poker game. That was my ruin. Now I am anxious, stressed, and miserable."

A new technician was put to work on the production line test station. "Just plug in the connector and read the voltage. If the voltage reads between 3 and 4 volts it passes. If not it fails, and you put it in the "fail" bin."

After his first shift he told his supervisor "I quit."

"What is the matter?" asked the supervisor, "the work can't be that hard."

"Oh, it isn't the work, that's easy. I'm going crazy with making all those decisions!"

One manager was bragging to another. "I have a great engineer working for me. Last week I gave him a project and he stayed up for six straight days, completed the circuit board design, finished the bill of materials and wrote a thousand lines of firmware.

His friend asked "So how far ahead of schedule was he?"

The manager said, "Ahead of schedule? Who ever heard of an engineer doing that?"

Lyrics to "Who let the Smoke Out."

Who let the smoke out
(whoo, whoo, whoo, whoo)
(whoo, whoo, whoo, whoo)

(whoo, whoo, whoo, whoo)

Who let the smoke out (whoo, whoo, whoo, whoo)
Who let the smoke out (whoo, whoo, whoo, whoo)

(whoo, whoo, whoo, whoo)

When the circuit was made, the product was sumpin' (Hey, Yippie, Yi, Yo)
And everybody proud of it all (Hah, ho, Yippie Yi Yo)
I tell the fellas "start the thing pumpin" (Yippie Yi Yo)
And the plug goes in to the wall

The smoke broke show brown

Who let the smoke out (whoo, whoo, whoo, whoo)
Who let the smoke out (whoo, whoo, whoo, whoo)
Who let the smoke out (whoo, whoo, whoo, whoo)
Who let the smoke out (whoo, whoo, whoo, whoo)

I see a little smoke puff–makin' some toast
Lights really dim in the town
Get blame off me, shame off me
Rollout is gon' take a bit longer
