'Community' photos: Troy (and Donald Glover) says goodbye in 'Geothermal Escapism'

"Community" is saying goodbye to Troy Barnes -- and actor Donald Glover -- in the upcoming episode, "Geothermal Escapism." But it can't be a simple farewell on a show like this. Instead, look out for post-apocalyptic festivities when Troy leaves Greendale.

The whole thing starts when Abed ( Danny Pudi) plans an epic going-away party for his best friend. Things quickly transform from there into a Thunderdome-style competition.

It all starts out normal enough with a small gift from Annie ( Alison Brie).
