Explain xkcd: It's 'cause you're dumb.
Title text: Amazon.com took a surprise early lead with 'Time required to transport a package from Iquitos, Peru to Manaus, Brazil' but then lost it at 'Minutes to skeletonize a cow'.
The Amazon River in South America is the second longest river in the world and by far the largest by waterflow. Amazon.com is a website that specializes in commerce and selling goods over the internet. The "round 14" suggest they are being compared in different criteria in a sort of competition. With such different systems, we can assume that most of those comparisons were similarly funny. The title text mentions two other criteria of comparison.
The measure of flow for the Amazon river (cubic meters per second) indicates the volume of water that passes a given point in the river at any second. To illustrate how much 220,000 cubic meters is, the comic shows a car parked next to 220,000 cubic meters of water. 220,000 cubic meters equals a cube with an edge length of 60.4 meters. By comparison the 0.9 cubic meters of goods that are shipped by Amazon.com seems very small (note that 0.9 cubic meters of goods per second is still a lot).
To illustrate this size, the comic shows an Amazonian fish (or possibly an Amazon river dolphin) investigating the packages.
Iquitos and Manaus are cities near the source and mouth respectively of the river; the title text suggests that it is faster to have a package shipped between the two than let it drift downstream. 'Minutes to skeletonize a cow' refers to piranha, an Amazonian predatory fish with a popular reputation of being capable of the mentioned act when hunting in groups, which has little basis in reality, though.

- Round 14
- Estimated outflow volume
- in cubic meters per second
- [A cube of water representing the outflow of the Amazon.]
- Amazon 220,000
- [A pile of boxes representing the outflow of Amazon.com.]
- Amazon.com 0.9
- Advantage: Amazon
I believe it is not about Amazon Forest, but about Amazon River. 18.104.22.168 (talk) (please sign your comments with ~~~~)
 Skeletonize a cow
Isn't there an urban myth that pirahnas can skeletonize a cow in under 2 minutes? 22.214.171.124 10:32, 25 January 2013 (UTC)
- According to , it's not myth - you only need few nets and few hundreds of piranhas. It was not mentioned how far they needed to go to get that number of piranhas, but I would suppose setting up that kind of practical joke can't take more that few days. -- Hkmaly (talk) 11:55, 25 January 2013 (UTC)
Does Amazon sell beef by any chance? I mean: while amazon.com can probably ship a package from Iquitos to Manaus, the Amazon can only nearly, because Manaus is situated a few kilometers upstream of a river branch where the package from Iquitos would float by. Makes me think whether there is a similiar comparison with skeltonized cows. Hence beef. 126.96.36.199 15:25, 25 January 2013 (UTC) madd
 Reason for comparison
I think the main reason for this comparison is the dispute over the .amazon TLD between Amazon.com on one side and Brazil and Peru on the other. --188.8.131.52 11:38, 25 January 2013 (UTC)
I assume you mean this article (or alike): http://www.dailymail.co.uk/news/article-2242994/Brazil-Peru-web-giant-Amazon-battle-amazon-domain-name.html

- Indeed, they are comparing who is “more worth” the domain name and this comic shows how to compare them --220.127.116.11 19:12, 30 January 2013 (UTC)
Just want to say that I always thought it was a mistake to add to the (generally) three-character traditional non-geographic TLDs that they used to have. This despite buying myself a .info when that first came out, mostly as a novelty similar to the acre of Moon. (But .aero? .museum? Really?) Still, can't begrudge them the drift to non-Western characters (just wish it'd been direct non-Western equivalents to .com, .org, .mil, .gov, etc... Anyway, what's wrong with just letting each national TLD logically and self-consistently expand upon their own existing standards (.co.uk, .com.au, etc) in a manner the locals would understand, and let significant metanational organisations (UN) do the same for their own subset of responsibilities in their own pseudo-national TLD. (You see, I over-think these things.) 18.104.22.168 16:20, 28 March 2013 (UTC)
 Is anyone else thinking what I am?
Its been a while since Munroe has given something seriously good/thoughtful.... I am getting the inner feeling that he is planning something big. Like BIG . Anyone here concurs with me? 22.214.171.124 14:18, 25 January 2013 (UTC)
I will second that. It has been a while since he has had any labour intentive jokes. 126.96.36.199 16:57, 25 January 2013 (UTC)
 Rounds 1-13
Am I the only one who wants to know what the other 11 criteria might be? 188.8.131.52 19:10, 25 January 2013 (UTC)
No. But we know 3 of them, right? So we just need 10 more. 184.108.40.206 18:52, 28 January 2013 (UTC)
We need 11 more. This is criterion 14, and we know 3 of them including this one. 220.127.116.11
