Can I be the first to say...
Eels, eels, eels, eels give it up now?
One man has calculated the power of electric shocks emitted from electric eels on the human arm - his in fact - all in the name of science. Kenneth Catania, a neurologist and biologist at Vanderbilt University, Nashville, Tennessee, repeatedly shoved his arm into a tank containing a small electric eel (Electrophorus electricus …
I can understand the researcher doing the eeldance once, but multiple times? Come on man, that's why you have graduate students!
Also, the circuit diagram shows the improper practice of touching the eel with the inside, or thumb-facing side of one's arm. Proper safety protocol demands the use of the outside, or pinky-facing, side of one's arm so that the involuntary contraction of one's muscles, should such an incident occur, will automatically move the arm in a direction that breaks the circuit.

No, he is only eligible for that if he manages to take himself out of the gene-pool, so he either needs to be killed or be rendered sterile by his experiments.
He could get an Honorable Mention though, like this guy though
7200 Volts And A Dim Bulb
then how long will it keep my smartphone powered for? And recognising that a live eel is going to be a bit inconvenient in my pocket (insert your own joke here), how long before I can have a stem cell injection to make my arm behave like this, along with an inductive link to my phone?

I'd not considered that, but its quite a cool idea. And you could do some entertaining party tricks with balloons full of hydrogen, Christmas puddings laced with brandy, fireworks. And you could "touch and kill" electrostatic sensitive devices, like the loud mobile phones of colleagues left on their desk to annoy everybody else with a cheesy ringtone.
Conversely, "relaxing in the gentleman's fashion" could carry certain risks.
"the power of the shock was calculated to be approximately 3.9 Watts – enough to make Catania flinch and pull away"
Electric fence energisers are rated in joules. I assume this is because energy is correlated with unpleasantness.
Mine runs at 0.8J. I'd rate it about 6 on the psychological damage scale, or "not doing that again, even for beer".
Yep, its a real shame that he didn't set up the experiment to include a storage scope so he could record the time element. Looking at some of the videos, it looks like the fish can sustain up to 2 seconds of pulses at an approximate 50% duty cycle although probably not a square wave. It does look though as if this little fish could possibly produce more energy than a 0.8J fence.
edit: Just found a video ( youtu.be/VGbj9Up4dvs ) showing one goading an alligator then killing it. Unfortunately for the fish, the gator dies with a death grip on its neck. The main thing is, it keeps shocking the gator continuously for just over 45 seconds, so several 10s of Joules involved.
Unfortunately around 40 years ago a pioneering science show produced by the BBC was mistaken for a new form of oddball comedy ... had people taken it seriously then perhaps we would have solved the problems of carbon fuel based transport and we'd all be traveling in the electrically powered hovercraft that they wanted to publicize using a natural supply of electricity. Sadly they did receive the support they needed to enable them to size reduce the power supply leading to the dismissive comment that "my hovercraft is full of eels".
