The science of the penis
Robert Lamb and Julie Douglas, of the Stuff to Blow Your Mind podcast, recently squirted out a two-part series on the penis.
But they didn't stop at humans, who, by the way, have the largest members in regard to body proportion, thank you very much. From scary two-headed monsters to freaky detachable insect schlongs, these episodes are both insightful and frightening.
Unfortunately, the How Stuff Works podcasts don't offer the ability to embed episodes, so if you're engorged with interest, you can listen to both parts of "The Penis Episode" via their iTunes page.
