It’s Halloween, which means well-marshalled snacks, sophisticated costumes, and a speech from The Senator – at least if party-planning machine Angela has anything to do with it.
But this year it’s Andy who takes charge of the entertainment, enlisting Cornell’s a capella group – nattily named Here Comes Treble – to perform. It’s a suitably scary surprise, at least for Dwight (“What lab did these little clones escape from?”).
Luckily he’s distracted by a yellow pill he finds under the sofa – “it’s not for worms or eczema like any normal pill” – and embarks on a mission to find the mentally unstable pill-taker.
And when the big Here Comes Treble finale Andy (a former Trebler) was hoping for doesn’t materialise, Erin is moved to intervene – despite her total bewilderment at the art of a capella. “When you’re with someone,” she reasons, “you put up with the stuff that makes you lose respect for them.”
