A onetime member of Andy’s Cornell a cappella group Here Comes Treble, Rob (finally) makes his debut in the Oct. 25 episode after the Dunder Mifflin boss gets wind that his frenemy is rewriting their musical history in a much-too-dissonant key.

The Office, meanwhile, kicks off its farewell season tonight at 9/8c.
