• Rahm Emanuel, meet Faux Rahm. Chicago’s mayor-elect on Wednesday made a $5,000 charitable donation in the name of Dan Sinker, a Columbia College professor who confessed to being the anonymous wit behind @MayorEmanuel, a Twitter account as hilariously and unquotably vulgar as the man himself. Emanuel joked that while reining in his rich vocabulary during the campaign, he found an outlet in reading Sinker’s tweets, so “now that he ends this, the ‘Calm Rahm’ may have to go away.” Sinker’s gift will go to an after-school writing program, the Sun-Times reports.

• Fred Grandy — the “Love Boat” star turned Iowa congressman turned morning drive-time talk-radio star — is leaving his gig as star of WMAL’s “The Grandy Group.” Grandy’s ratings have lagged behind the station’s other conservative hosts, and he has clashed with management for months over how to boost them.
