Penis Economics

Annals of Improbable Research posted blurbs of a couple of interesting-looking papers on Facebook.

One paper, according to the first sentence of its abstract, "explores the link between economic development and penile length between 1960 and 1985."

Another paper discusses etiquette versus effort in door-holding, which some of you know quite well is actually very important to me. Here is a link to the actual paper. I should mention, though, that my purpose in doing this is not to minimize total effort; I do it because it's the right bloody thing to do!
