Holy Guest Star Alert!

Whether it was planned to make us forget about Donald Glover's absence or not, Community Season 5 Episode 6 featured a number of familiar faces in high-up Greendale roles.

There was Nathan Fillion as a janitor. Paget Brewster as the IT woman. Robert Patrick as the man in charge of parking. Katie LeClerc as a deaf love interest for Abed.

The half hour centered on Hickey and Annie trying to fight through the school's red tape and on each of these actors briefly stopping by to make their lives difficult.

Britta also tried to spoil a Game of Thrones-type show for Abed. IT was very cruel.
