Some celebrities simply shouldn't be given a platform with which they can express themselves at any given time. Twitter makes the possibility for boundless self-expression available, but that doesn't mean that everyone should speak their mind without evaluating the content that comes out of their mouth first. Celebrities, in particular, are endowed with the rare gift of inspiring others with their words; their fame gives them the chance to make an impact that most people could not make single-handedly. It is thus disappointing and embarrassing when a celebrity makes a fool of himself or herself on Twitter. The tweets below are quoted exactly as they appear on Twitter, spelling errors and all, for your enjoyment.

   Oh, Tyra Banks. We've become well-acquainted with your self-obsessed, erratic behavior via America's Next Top Model, and now with Twitter's instantaneous updating technology, we can have a more intimate view of your everyday thoughts before your publicist has time to do damage-control. With tweets like, "It hurts on the pinkie side of my hand…" and "this fab Xmas music makes we wanna run to the North Pole and smize to Santa," we are ready to unfollow you. In case you don't know, "smize" is Tyra's coined term for "smiling with your eyes" and it's her trademark as a model. And there is, of course, our favorite, creepiest tweet posted by Tyra to date: "I just saw the most beautiful young girl. About 5 years old. Lovely hair, lovely smile, lovely face. A stunning girl. She has albinism." For some reason, we can't help but read that quote in the voice of Hannibal Lecter.

2. @parishilton

   Paris Hilton has, quite possibly, the most uninteresting tweets of any celebrity. Perhaps this stems from the fact that she has no real reason to be a celebrity. She posts the tweet "11:11 – Make a wish…" verbatim on an almost daily basis, and is prone to inform us of when she's going to bed and waking up. Yawn. That, and her vapid, blonde girl tweets like, "I love shopping! : )-" put her prime on our list of celebrities to unfollow on Twitter.

3. @heidimontag

   Heidi Montag's tweets are exactly what you'd expect them to be, but there's something about reading them on a page instead of hearing her speak on The Hills that truly makes us cringe. Heidi posts "I have sun poisoning from tanning too much!!!" and "giving myself a soft tissue breast massage. Ladies we have to keep those implants soft." We may have known Heidi's breasts were fake, but her posts show us exactly how close she is getting to becoming a human Barbie. We agree with you, Heidi, when you post, "These fumes in nail salon are defiantly getting to my head." Maybe it's time to lay off the silicone and acetone.

4. @cher

   Cher has made it abundantly clear with her tweets that not only does she not have the vaguest sense for technology, but she is also incredibly illiterate. Favorites include, "Gotta go !???????pls Tell me where 2 find little symbols again ( pretend youre tak''n2 your mom s-p-e-a-k Slowly) I?them ! Yeah I'm mature" and "1more thing,im Lucky couldn't have been here 46yrs w/okarma & U all! I'm "RealComplicated"Sometime??sometime ? ! It's just me!" What exactly is she trying to say? The only excuse for typing this poorly is if you're still using T-9 to type on an old Nokia cellphone. Shame on you, Cher.

5. @russellcrowe

   Russell Crowe works out. A lot. In case you wanted to know exactly when and which repetitions he's doing, his Twitter is nothing but a log of robotically stated workout routines. For example, in one 24-hour span, Crowe posts both, "50 lengths of the pool , 1km." and "15 min walk, 35 min gym, 14 lengths of the pool, 30 min walk." There is at least one post detailing his exact regimen for every day of the week. Crowe may have not had a lot of acting work over the past year or so, but he clearly has plenty of time to work out on his ranch in New Zealand.

6. @jimcarrey

   The comedian's Twitter is full of strange, yogi-like credos and references to his art studio, which he calls "The Church of FFC." The strangest is his fascination with the word "Boing." He's made a number of posts concerning this word, for example, "#Boing an acronym. Bouncing On Inspiration's Neverending Geyser, Believing Only In Natures Grace, to name a couple. Now U try ?;^)" and later, "To thine own #Boing be tru! ?B^]." We're not really sure what to make of Carrey's quirky tweets, but we hope he isn't pulling a Tom Cruise and going over the deep end.
