October 15 - The Red Headed Stranger

As more and more animals join the list of the world's endangered species, and as more and more of the world's endangered species go extinct, it was a shock when a team of zoologists discovered a new species of bear in in the foothills of Montana.
The bears were the size of grizzlies, with coats of an amber so bright it was hard not to call them red heads.
A male of the species was transported to the Zoology Department at University of Montana to be studied. Dr. Kenneth Urbana, the researcher who was heading the study, nicknamed the bear Willie Nelson both because he was a huge fan and also because the bear was a living, breathing embodiment of his favorite Willie Nelson album, The Red Headed Stranger.
Unfortunately, Willie Nelson didn't always share Dr. Urbana's love of his namesake's music, not even the album that was serving as the ad hoc name for Willie Nelson's species until they came up with something better. In the first few days of the study, every time Dr. Urbana played The Red Headed Stranger in the lab, Willie Nelson would growl angrily, throw a fit, or sit disconsolately in the corner. Most other bears that Dr. Urbana studied were calmed by music of almost any kind. Not Willie Nelson. He often seemed agitated by music, and not just Willie Nelson's.
But he wasn't always this way. A few hours after almost every period of melancholy or rancor, Willie Nelson's mood would brighten considerably when Dr. Urbana played Shotgun Willie or Teatro instead. This prompted Dr. Urbana to think that it was the music that was impacting Willie Nelson's mood; however, further study indicated that that wasn't necessarily the case. In fact, it was impossible for Dr. Urbana to put a finger on exactly what triggered Willie Nelson's dramatic changes in temperament.
The only thing he knew for sure was that ups and downs were the norm for Willie Nelson. Every day was filled with unpredictable changes in his emotional state. This gave Dr. Urbana and his team plenty to keep them busy, and it ultimately helped them come up with a name for Willie Nelson's species. Because all the other red headed bears that were being studied in different labs around the region exhibited the same erratic mood swings as Willie Nelson did, it was the consensus within the scientific community that they should be called bipolar bears.
