'Boy Meets World' meets 'Grey's Anatomy': Mr. Feeny will administer the test

Fee-hee-heeny!

"Boy Meets World" fans, rejoice! Mr. Feeny (okay, his real name is William Daniels, but we'll continue to think of him as Mr. Feeny until we die) is coming to "Grey's Anatomy."

TVLine reports that Daniels has been cast as the doctor who will oversee the medical board examinations at Seattle Grace in an upcoming episode.

The episode, which was directed by series star Kevin McKidd, doesn't end well for all of our favorite characters. Sandra Oh tells us that one of the Seattle Grace docs won't pass the test, and another will walk out.
