The Stud of San Diego

It's not every day that a tortoise features on The Late Show with Stephen Colbert.  It's even less often that the subject is that tortoise's sex life.

Still, such is the fame of Diego, a Galapagos tortoise from the San Diego Zoo, that he earned such an honor.  Diego has been all over the press lately, having achieved a two-fold immortality.  The first part is for helping his species (or subspecies - Galapagos tortoise taxonomy is confusing as heck) pull back from the edge of extinction through his... ahem... Herculean efforts in a captive-breeding program.  The second has been through the endless headlines he's been able to generate, all of them effectively saying "Tortoise retires after having enough sex."  Hell, he even made the New York Times a few years back.

Meet Diego, the Centenarian Whose Sex Drive Saved His Species

Diego has recently been returned to the wild from which he was taken decades ago, having done his part to help save Galapagos tortoises from extinction.  I wish I could say that he'll probably enjoy this "retirement," but after decades of living what really is a male tortoise's dream existence, I can't say that with a straight face.
