Los Angeles Lakers, National Basketball Association (there's not even a distant second)
And oddly enough, I don't have a least favorite National Hockey League team. The closest I come there is the Dallas Stars, and that's because they left Minneapolis/St. Paul bereft of an NHL team for many years.
Other interesting things about me:
I think the Emmy Award is the coolest of the four major entertainment awards given in the United States.
I have been a contestant on Jeopardy!. In Episode #5750 (taped July 28, 2009, aired September 18, 2009), I came in second place to defending champion Gary Bechtold and won $2,000. Answer to the Final Jeopardy! question - Who was Edward Lear?
I was also a contestant on Who Wants to be a Millionaire. On an episode recorded November 2, 2011 and broadcast on March 2, 2012, I won $5,750. I was stumped by a question about who owned Dollywood before Dolly Parton owned it. The correct answer was Art Modell.
I participated in National Novel Writing Month, or NaNoWriMo, seven straight years (2004-10). Which means I have seven very bad novels to my credit (or discredit).
