Nathan Fillion will be guest starring in an episode of NBC's Community during its fifth season.
According to Entertainment Weekly, the Firefly star will play the head custodian for Greendale Community College, Bob Waite.
The NBC comedy will see several other guest stars this season, including Walter Goggins, along with the returns of Rob Corddry, LeVar Burton and Jon Oliver.
Deadline. who was the first to report the news, says that Annie (played by Alison Brie) and Professor Hickey (Jonathan Banks in a guest star role) must team up to contend with the clever Bob.
Fillion is currently starring in the ABC drama Castle, which is now in its sixth season.
While the show will get to enjoy Fillion, it won't be seeing much more of Donald Glover, who plays Troy. The actor will only be appearing in five episodes for the show's fifth season.
Glover wasn't interested in doing a full season, plus he is busy with his musical career as Childish Gambino.
