Take a break from the drudgery with some of these jokes, song parodies, anecdotes and assorted humor
that has been collected from friends & from websites across the Internet. This humor is light-hearted
and sometimes slightly offensive to the easily-offended, so you are forewarned. I have taken care
to censor "humor" with overt sexual overtones (or undertones), degrading political taunts, and hateful
tirades, so it is all workplace-safe. I have also tried to warn of any links that will result in audio
clips so you can take appropriate precautions. Please send any potential candidates for this humor
page to the e-mail link above.

So, how many AA batteries would it
take to power a standard adult human for one day?
A Manganese/Alkaline AA cell it rated at about
2.4 amp-hours. If we assume 1.5 volts average this gives approximately 3.6 watt-hours (slightly optimistic). Since
there are 3,600 seconds in an hour this is equivalent to 12,960 Joules.
A human consumes about 2,000 calories/day. A dietician calorie is equal to 1,000 engineering calories. A calorie
is equal to 4.2 Joules. Therefore this is equivalent to 2,000 * 1,000 * 4.2 = 8.4 * 106 Joules per day.
Dividing one by the other you will need about 648 AA cells to power a human for one day.
This assumes that
the power from the AA cell will go through the same inefficiencies as the chemical processes in a human. (A human
runs at about 20% efficiency chemical energy to mechanical energy). If we can circumvent this inefficiency we
would only need 20% of this number of cells - say 130 cells.
