People follow celebrities on Twitter for entertainment.  And, maybe to feel like they’re Facebook friends with the person.  Often, celebrity tweets are as mundane as typical Facebook status updates, but some of them understand it’s a way to reach hundreds of thousands of people.

Unfortunately, some celebrities forget that too, and some of them say things they wish they could take back.  Public figures have been humiliated, reprimanded and fired for things they’ve said on Twitter.  So, we’ve decided to make a little list of celebrities who should think twice before tweeting anything ever again.  These are in no particular order.

-Gilbert Gottfried: In terms of the mainstream public, this comedian with the grating (to some) voice has been largely under the radar in recent years, with the exception of voicing Aflac the Duck.  However, he lost that gig earlier this year when he tweeted some ridiculously crass comments about the Japanese earthquake and ensuing tsunami disaster.  A sample: “I just split up with my girlfriend, but like the Japanese say, ‘There’ll be another one floating by any minute now.’”  Ummm, really, Gilbert?

-Roger Ebert: Anyone who follows Ebert on Facebook knows he’s fun to read about.  He often posts cute pictures from Hollywood’s past and gives fascinating tidbits about his career.  All it takes is one time, though, to really piss people off.  His comments about Ryan Dunn’s car accident recently were divisive.  He certainly had a point about driving drunk, but his comments about Dunn rubbed people the wrong way.  Calling him a jackass may have been accurate, but poorly timed.  Unlike Gottfried, though, people were quick to forgive.

-George Lopez: This guy can be hilarious.  But when you call someone who’s struggled with weight problems a “pig”?  Um, no, no, George.  Okay, so this didn’t happen on Twitter, but it very well could have.  On his show, Lopez referred to Kirstie Alley, who was competing on ‘Dancing With The Stars,’ this way: “She did a nice job, her little hooves tapping away.”  Alley responded via Twitter, and Lopez eventually apologized.

-Anthony Weiner: We don’t really need to say anything beyond that, do we?

-Charlie Sheen: Reading his tweets is like a car accident.  You cannot.  Stop.  Looking.  At the peak of his Tiger Blood Winning Torpedo Goddess Tour Nonsense, he tweeted stuff like,” My sons are fine… My path is now clear… Defeat is not an option..!” Mmmkay.  He set records with his legion of followers, but it’s unlikely it can restore his reputation.

-Kurt Sutter: The creator of ‘Sons of Anarchy’ and the husband of star Katey Sagal took to Twitter after he, and his wife, were dissed by the Emmys.  The show got no major nominations, even though Sagal looked to be a possible nominee for Best Drama Actress.  His response on Twitter?  “Best part of not getting an Emmy nod, now I don't have to pretend I give a sh!t about the profiteering douchebag academy.”  Most of his subsequent tweets were more graphic and crass, but he later backed off, saying it was all kidding around.  Do you buy that?

Andy Dick: This is just kinda sad.  The troubled celebrity recently tweeted, “My alcohol monitoring ankle bracelet is still securely fastened to my ankle for many more months to come. Enjoy one for me, fine drinkers!"

Chris Brown: He’s had many a Twitter rant, but in December 2010 he got into an online feud with B2K member De’Mario Thornton — a.k.a. Raz-B.  In the exchange, both used offensive homophobic slurs, among other slings of insults.  It did not help Brown’s reputation, but not much could hurt it at this point.

What do you think?  Who are the worst Twitter offenders?
