Some opinions are so far-fetched that they deserve to be ridiculed. The conspiracy theory that something other than airplanes toppled the World Trade Center towers on Sept. 11, 2001, is a classic example.

It’s no surprise, then, that Pittsburgh Steelers running back Rashard Mendenhall earned scorn for tweeting about 9/11 after the United States killed al Qaeda leader Osama bin Laden. Mendenhall said both that he has “a hard time believing a plane could take a skyscraper down demolition style” and that “we’ve only heard one side” of the bin Laden story. He deleted the former tweet after public outcry.

UPDATE, July 19: Mendenhall has sued Hanesbrands for $1 million because the parent company of Champion dropped its endorsement deal with him after Mendenhall’s controversial tweets. “This is about whether he can express his opinion,” Mendenhall’s lawyer said.

Mendenhall stopped tweeting a few days before news of the lawsuit broke.

UPDATE, Dec. 7: Mendenhall finished at No. 6 on Time’s list of this year’s worst tweets.
