justin bieber hits a glass door
From bumbling into glass doors to clumsily escaping from fans on a Segway to getting hit with a water bottle on stage, Justin Bieber has generated some excellent bloopers. When you're in the public eye as much as the Bieb is, a normal human tendency to make mistakes gets exaggerated by YouTube paparazzi.

Well, his loss is our hilarious gain. Take a trip with me through the history of Bieber's most entertaining fails, ending with the water bottle video that's currently the hottest thing on YouTube.
Here's the first time Justin was caught walking into a glass door. I have to give him credit for holding it together and joking around for the cameras when that looked like it really hurt!
Here's glass door incident number two. They should just give this kid a special non-glass exit, for his own safety. Bieber and transparent doors don't mix!
In this video, Justin attempts to escape a throng of screaming fans. Unfortunately, he's using a Segway. Bieber, you'd probably be a little faster on foot, buddy ...
Playing a celebrity quiz show during an interview in New Zealand, the Bieb misheard a question, and the host didn't repeat the whole thing. The result: it looked like Justin Bieber didn't know the word "German."

Of course, it's debatable whether it's Justin's fault for not paying attention, or the host's fault for failing to repeat the part he actually missed.
Some peopleon YouTube are calling Bieber's ceremonial first pitch for the Chicago White Sox a baseball fail, but I don't know. I've seen worse first pitches from full-grown adults. At least Justin was able to reach the plate!
And now, the moment you've all been waiting for: Justin Bieber getting hit with a water bottle on stage. He shrugs off the undeserved projectile with good humor, but I have to admit that the slow motion replay is pretty funny.
