We haven’t confirmed or denied this yet. Marley23 only stated that female pigs didn’t experience orgasm. Males certainly ejaculate, and possibly experience the sensation of orgasm during this time as well. I’d say the jury is still out on this one, though I feel 30 minutes may be excessive.
That’s true. I apologized.

In case this catches anyone else’s eye, yes that’s wrong – It’s 271 million seconds – but the calc uses the right value.
I was talking about chemical energy (and I assume the OP was, as well), you smartass. But ok, let’s do it your way. Let’s assume the average fart is 1/3 cubic foot of methane. Since methane has a molar mass of 16.04 g/M, at STP, that is 22.4 liters or .79 cubic feet per mole which works out to 4.22 x 10[sup]-3[/sup] kg. Plugging this in to e=mc[sup]2[/2] = 3.79 x 10[sup]14[/sup] ergs or approximately 35,000 BTU. Not even close to atomic bomb levels.
Oops, mea culpa. Mixed up cgs with mks units. It’s actually about 35,000,000,000 BTU. Which is still not quite at Hiroshima atom bomb levels, being low by an order of magnitude.
I see someone just got an email account and believes everything they read in their inbox. 
Duckster, the purpose of my post is to verify those informations, which doesn’t mean I believe them. Since some of them are a little bit funny I tough it was a good idea to check them all together. If you don’t think so, it is your rights.
But please, do not participate in the thread the way you just did, this isn’t funny and I don’t think people like that.

P.S. Maybe I’m taking that too personnal, but since I’m in computer business for 10 years, I just don’t think it’s funny. 
The pig thing is very commonly disseminated (SORRY!) in e-mails, and usually specifies females. Again, see the column - I can’t envision any male, excepting perhaps some very advanced yoga, sustaining an orgasm for 30 minutes, or anywhere near it.
Easy there, homerggg. Duckster wasn’t trying to be mean or imply you are unintelligent. It was only a joke; you can tell by the smile.
An unconfirmed Calories Burned Calculator has me burning 190 cals an hour for light manufacturing work while standing, 126 while sitting. Are you sitting or standing while knocking your head against the wall? If standing, I would think head banging would involve more than just the head and neck, which may fall under Calisthenics - light or moderate, which is more along the lines of 294 calories in 1 hr. Often considered analagous to banging your head against a wall is attending meetings, which comes in at 126 calories in 1 hr.
Over all, I would suspect that for a 6’0" 185 pound male, head banging would come in slightly higher that 150 cal/hr. Unless it was the “mythical” headbanging that can be found at management meetings, in which case it comes in at slightly under. The difference can be easily made up by calories burned due to synaptic firing while actively wishing death on clueless a-hole of a cow-orker.
Well actually the farting one has the potential to be waaaay off going by the assumptions posted here so far - two of them are really off-base:
- volume farted… the average man expells a bit over half a liter of gas per day, in about 15 “intervals” (which you could say last ~ a second each). 600cc/15 = 40cc/fart.
Using 1/3 of a cubic foot/sec, you’re getting 9,439cc/fart, only about 236 times more than the average person can do. - assumption that a fart is pure methane… not even close. Many farts contain trace amounts -if any- methane. There’s some H2S or other sulpher compounds, nitrogen/air, lots of stuff. I’m not gonna spend the afternoon researching what’s in a fart, but I’d say the energy value has been greatly overestimated here.
Q.E.D., sorry, I just read it again and again and you’re right about the post, it was just a joke…
So we can say that 150 Cal/Hours is pretty much right for the head-knocking thing.
Marley23… sorry, but I do not understand your post (too many words I can’t understand… english is not my first language). Are you saying that no male animals can sustain an orgasm for 30 minutes ?
Q.E.D. Well we’ll stay with the chemical energy for the fart question.
homerggg
I woulda said that MOST animals have sex just for fun. Lacking a level of conciousness to understand the choice between procreating and not, they are doing it because it feels good to them. Certainly, the average dog humping my leg is not doing it because he thinks he i s procreating (although there will be those who say that is a dominance behavior.) My point is, nature made if fun so as to ensure that animals would do it.
Yes. I also said that I don’t think male HUMANS can do this either.
You don’t know me well.
homerggg
My apologies homerggg. However, your post is very similar to other threads where the OP posted stuff from email making the rounds at the time. And in some of those threads IIRC, comments back were not always as light-hearted as mine.
You’re new here. I’m in IT, too, and we rarely taken anything seriously. 
BTW, Thanks Q.E.D.
No. At least not the boars. Unless the sows are engaging in masturbation we have to assume this factoid is total piffle.
I’ve been involved with collecting semen from boars for AI. This involves mimicking normal copulation, and “a four-phase ejaculation follows in a few seconds, taking 5 to 10 minutes to complete.” (http://www.dpi.qld.gov.au/pigs/4543.html)
So while a boar’s orgasm lasts longer than a human’s, it’s nowhere near 30 minutes. The whole act takes less time than that.
I’m also going to call Cecil’s column into question. Stephen Jay Gould, in one of his essays made note of the fact that every placental mammal that has been manually stimulated has achieved orgasm. While Gould notes that orgasm doesn’t seem to occur in any of these species during normal copulation, the evidence does seem to directly contradict cecil’s assertion that “, do not experience the Big O”.
No, quite the opposite in fact.
Human are the only species that has sex for any reason other than fun. Some humans will have sex for the sole reason of procreation, but we are the only animal to do this. There is reason to suspect that any other animal species links the act of copulation with reproduction. The sole reason other animals have sex is for fun, and that includes dolphins.
Aren’t humans beings are the only species that know the cause and effect of reproductive sex? I can’t imagine the alley cats in my neighborhood are thinking about making a whole lot of unwanted kittens.
“Hiding the sausage” is probably fun for alot of animals. Vesides instinct, why else would they do it?
Oops, not mine either. I made the mistake of squaring in the decibel computation, which means my numbers were twice as big as they should be.
In other words, an eight-year scream to warm 200 mL 1 degree only needs to have 65 dB of power. To warm 20 degrees would take 78 dB, so it was about right.
And yes, 80 dB isn’t the loudest sound a human can make; I just pegged it as the volume of a sustained yell, rather than a shriek. You could get boiling water in a year or so at 100 dB.
I still object to the meaningless precision of the list. And the obvious thing - just like farting won’t level a city, this feat isn’t practical since the water cools off faster than you can heat it.
I think using chemical energy is cheating - surely what we compare is the energy released by the fart?? That is, the energy to move the gas…
OK, let’s pull some numbers out of my ass!
Assume every second someone farts 1g of gas at 0.1m/s. Then energy/s=5*10[sup]-6[/sup]J/s, so energy/yr=150J/yr.
Energy of Hiroshima bomb=510[sup]13[/sup] so you would have to fart for approx. 310[sup]11[/sup] years.
My assumptions are a bit random, and I might have messed up the calculation (QED?) but my time is:
An order of magnitude greater than the age of the universe
And theirs is:
6 3/4 years
