I don't even know where to begin. Todd Barry as a harried Other Music employee. Ted Leo in drag. Jon Wurster inhabiting the role of "A.C. Newman". Mike Lisk (aka @APMike) turning in a truly deranged performance (though I'm not sure how much of it was performing and how much was Mike being Mike). "Independent Spirit Award winner" Kevin Corrigan, looking very Kevin Corrigan-y. Horatio Sanz, Julie Klausner, Wyatt Cenac...hold on, let me catch my breath...
Plus cameos from many other comedy and musical giants, and enough Best Show-related easter eggs to delight sharp-eyed completists (like me).
Oh, and it starts with a trailer for a fake movie starring Paul Rudd and Bill Hader (Expectant Dads). If you want more than this video can give you, you must eat diamonds for breakfast, pal.
