Ben Carson has said a number of unusual things in his quest for the White House, but the latest—his belief that pyramids were giant grain silos rather than tombs for Egyptian pharaohs—seems to have pushed a lot of pundits into straight-up ridicule of the GOP frontrunner. 

MSNBC's Morning Joe has questioned "whether he has the temperament, whether he has the character to be President of the United States.” Fox News' Shep Smith is straight up mocking him. And NY Mag's Jonathan Chait has flagged a fascinating quote from an interview Carson gave to CNN:

In May, Carson told @JohnJHarwood Obama is a "psychopath" because he claims unemployment rate is 5.5% pic.twitter.com/6vvhu7tLBI

In other recent Carson news: Politico reveals he fabricated a story about being accepted at West Point and Carson 2016 has released a rap radio ad. Time magazine notes:

Called “Freedom,” the 60 second rap by the rapper Aspiring Mogul contains bits of Carson speaking throughout.

“Heal (vote, vote)/ Inspire (vote, vote) / Revive (vote, vote)/ Ben Carson 2016, vote and support Ben Carson, for our next president, it’d be awesome,” Aspiring Mogul raps.
