We've had a lot of posts here the past couple years about Knut, the polar bear sensation of the Berlin Zoo. But it appears his proverbial 15 minutes of fame are up. He recently celebrated his second birthday with little fanfare and the zoo that cashed in on his cuteness as a cub is now looking to relocate him to another zoo because he's grown larger than what his pen can comfortably hold. ABC News has all the details here. The Sunday edition of Good Morning America actually carried a segment on how zoo's capitalize on the cuteness of their newborns to increase their revenues.
