Who Tweeted What? Take the Celebrity Twitter Quiz

LaBeouf tweeted this statement 22 times. He also scrawled it on a paper bag he wore over his head at a movie premiere. No one knows why.

Rapper Lil Jon left little to the imagination when he -- in all caps, no less -- disclosed his epic bowel discomfort to the wide world of Twitter. Don't even get me started on the irony of him being stuck behind a bus "dropping kids off." If only they'd been deposited at the local swimming pool ...

First of all, WHAT'S UP WITH THE ALL CAPS TREND? ENOUGH ALREADY! Moving on, after being accused of attempting to hook up with a teenage girl, actor James Franco decided to cover his virtual butt by playing it off with a bit of Twitter-based humor. Even Charlie Sheen knows better than that, James. For shame.

Is anything more chuckle-inducing than smoking crack? Not according to Mr. Half Dollar, who at least managed to include half of the necessary apostrophes in this tweet.

Dirty innuendo is so much funnier when it's unintentional, like this tweet from world-renowned televangelist Joel Olsteen. Olsteen hastily deleted it once the jokes started flying.

Strangely, that was from Justin Bieber.

Whatchu got planned Katy? Apparently, in her universe the songstress equates pimples to shooting stars and four-leaf clovers. Hope this tweet didn’t come with a Twitpic.

Cher has put out tweets that similarly confused various social media outlets, but R&B singer Ashanti's the brainchild behind this one.

Yes, Kanye … because Kim Kardashian West's clothes are what could potentially embarrass you. Not your Jupiter-sized ego or foul lyrics, or anything.

Shepherd has high expectations for those immediate moments following morning wake-up, apparently. Ever heard of probiotics, Sherri? But let's cut her some slack. She later tweeted a clarification: "not my REAR plugged ... my RIGHT ear is plugged."
