With the fast start that the NBA season began with, players did not get in the normal training camp time and had a very short preseason.
As was expected, some players were not as prepared as they should have been for the start of a season, and some players and teams have not started out the way that they have wanted.
Like the picture above of New Jersey Nets forward Shelden Williams dunking on his own face, here are videos of 10 of the most embarrassing on-court miscues so far this season.
As if he has not endured enough criticism from fans for his highly publicized personal life, Kris Humphries also has a big missed dunk attempt this season.
Humphries and the New Jersey Nets lost this game 98-82 to the Cleveland Cavaliers on New Year's Day.
Caron Butler of the Los Angeles Clippers takes a shot where it counts from Gerald Wallace.
As Wallace tries to save possession, Butler is in the wrong place at the wrong time.
After a few minutes, Butler felt better and the Clippers beat the Portland Trail Blazers, 93-88.
Butler finished the game with 19 points.
Jason Richardson of the Orlando Magic has won the NBA Slam Dunk Contest twice in his career.
That did not show on this dunk, where he just didn't get high enough.
The Magic beat the Toronto Raptors, 102-96.
Los Angeles Lakers center Andrew Bynum grabs a big rebound and throws an outlet pass out to the wing.
The pass catches teammate Troy Murphy in face.
The Lakers beat the Houston Rockets, 108-99.
In a game against the Charlotte Bobcats, Miami Heat superstar LeBron James throws down a monster dunk that doesn't make it all the way down.
It appears that the ball bounces off of defender Gerald Henderson's head for a long rebound.
The Heat squeaked by the Bobcats for a 96-95 win.
Utah Jazz point guard Devin Harris chases a loose ball into the front row of the Staples Center.
The embarrassment was not for Harris, but for the front row fan that the announcers have some fun with.
The Jazz lost the game to the Los Angeles Lakers, 96-71.
Late in the first quarter of a game against the Denver Nuggets, Los Angeles Laker forward Metta World Peace takes off for a big dunk that skips over the rim.
The Lakers still won the game, 92-89.
Brendan Haywood of the Dallas Mavericks scores an unlucky basket in the wrong hoop against the Oklahoma City Thunder.
As Russell Westbrook goes up for a wild shot, the ball deflects off of Haywood and into the hoop.
The Mavericks lost the game by two points, 104-102.
Washington Wizards rookie Chris Singleton takes off on the fast break for a monster jam.
Singleton jumps from in front of the free-throw line but comes up empty on the finish.
The Wizards also came up empty, as they lost to the New York Knicks, 99-96.
Denver Nuggets forward Danilo Gallinari thought he had a late game-tying layup but came up with nothing instead.
Gallinari gets ahead of the defense for a seemingly routine layup that takes three bounces off of the rim and falls to the side.
The Lakers added a free throw to win the game, 92-89.
