A search for "slimy" and "Rhodes Scholar" turned up this item. Baldilocks tells the story of an educated and successful young black man who wanted to give back to his community and applied to teach in the metro Atlanta area. He was turned down -- here's part of the rejection letter:

"Though your qualifications are quite impressive, I regret to inform you that we have selected another candidate. It was felt that your demeanor and therefore presence in the classroom would serve as an unrealistic expectation as to what high school students could strive to achieve or become. However, it is highly recommended that you seek employment at the collegiate level; there your intellectual comportment would be greatly appreciated. Good luck."

Appalling -- read the whole thing.

(Oh, there was just an incidental Rhodes Scholar reference in the comments.)
