The best part of this clip from last night's finale of PBS' Sex in the Wild is when anatomist Dr. Joy S. Reidenberg, standing a few yards away from a dead beached sperm whale, shouts, "Can you see the penis?!" Penis ahoy!

Another classic episode of the best show on television, PBS' Sex in the Wild, aired last night. This one focused on kangaroos, whose engorged S-shaped penises look like earthworms. If I were a girl (or gay boy) kangaroo, I would take one look at one of those Cronenbergian appendages and say, "Crikey!"

"The team needs to act fast to gain access to the bull's penis before it retracts back into its sheath" is the first thing you hear in the preview above for the new PBS series Sex in the Wild, which premieres Wednesday. And that's all you need to know about whether or not this clip is for you, because really it is all about gaining access to a four-ton elephant's penis. And extracting sperm from it, while the elephant dozes gently. And measuring it (1 meter, 40 centimeters). And its "natural searching response," which causes it to jump like a fire hose being turned on. And stimulating the elephant's prostate.
