Penguins on treadmills... for science!

(CBS) - Want to watch a penguin waddle his way through a treadmill?

What if I told you it was for science? (I had you at penguin, didn't I.)

Well ladies and gentlemen, look no further. According to the YouTube video's info box, scientists wrangled up a bunch of king penguins so they could strut their stuff on a small treadmill. The mission was to determine how much energy they needed to expend "in order to maintain different heart rates."

I believe operation happy feet was a complete online success.
