First, check out this YouTube.com video that shows former Van Nuys High star Gilbert Arenas answering the challenge to a one-handed shooting contest (it's 10 minutes long, but worth your time):

WASHINGTON (AP) -- Perhaps the Washington Wizards are showing the effects of a little too much Gilbertology. Two days before what Gilbert Arenas has proclaimed will be his next 50-point game, no one wanted to
say much about it.
“I’m not going to comment on that,� coach Eddie Jordan said. “He talked about that. That’s for him. I’m concerned about how we should perform as a team.�
“We’re going to have no distractions,� forward Caron Butler said. “We just want to play basketball and win the game. Obviously, he made statements, and it is what it is.�
“Hopefully he doesn’t get too excited — like he did for the Lakers game,� guard DeShawn Stevenson said.
Arenas himself was a no-show for reporters following Friday’s practice. Anyone who wanted to know his latest thoughts had to be content with a new entry on his nba.com blog, posted under the heading “Time to Get
my 50 Points vs. Portland.�
“Even if you don’t watch the game, you’re going to look at the box score to see what happened,� Arenas wrote. “My last one o’clock game was 51 against Utah. So I’m feeling pretty frisky.�
Arenas has vowed to score 50 against the Trail Blazers on Sunday as payback for anyone who might have had anything to do with his not making the U.S. national team for the world championships last summer. Phoenix coach Mike D’Antoni and Portland coach Nate McMillan served as assistants on that team, and Arenas unleashed his frustrations against D’Antoni by scoring 54 against the Suns in December.
But Arenas and the Wizards have not played well recently when the Agent Zero hype machine has been running full throttle. When Phoenix made the return trip last month, Arenas started 1-for-6 from the field in a 22-point loss. Last week, Arenas admitted to psyching himself out by acting too serious before a rematch with Kobe Bryant and the Lakers; Arenas missed 20 of 29 shots in a 16-point loss.
Furthermore, the Wizards have lost three of four since forward Antawn Jamison went down with a knee injury, including a 27-point loss to San Antonio on Wednesday in which Arenas struggled again. More than anything,
the Wizards need a win to regain the momentum that has put them among the top Eastern Conference teams and earned All-Star nods for Arenas, Butler and Jordan.
“Coach is just saying the main thing is to win games — we’re not going to feed into an extra hype,� Butler said.
But Arenas has become a bottomless well of quirks and anecdotes, and there always seems to be something new. A quiet Friday received a mild jolt when Time magazine released an article in which strength and conditioning coach
Drew Cleary said of Arenas: “I hope he never goes to a party where there’s cocaine dust in the air. If he ever gets the flavor for it, he’s so obsessive-compulsive, that will be the end of his career.�
The Wizards clarified Cleary’s remarks: “Drew used a poor analogy when describing Gilbert’s workout routine, but the focus of the article is about what an outstanding player Gilbert is and his incredible drive to be the best,� spokesman Zack Bolno said.
