Damn, I may have to give Kelsey Grammer’s painfully unfunny fall comedy Hank another shot.

Lauren Graham’s ex-Gilmore Girls BFF Melissa McCarthy — who just wrapped a two-year run as a member of Christina Applegate’s entourage on Samantha Who? — is joining the ABC sitcom on a recurring basis, sources confirm to me exclusively.

McCarthy is playing Dawn, the wife of David Koechner’s Grady and sister-in-law to Grammer’s Hank.

BTW, I heard much of the dreadful Hank pilot was reshot — another reason I’m keeping an open mind about the show.
