Last week, we showed you the first photos from Community's new animated episode, "G.I. Jeff", an homage to the classic 1980s series G.I. Joe, which airs Thursday, April 3 at 8 PM ET on NBC. G.I. Joe fans know that every episode ended with a public service announcement (PSA), where the characters dished out important lessons for their young fans, and Community's tribute is no different. Today, NBC released the PSA for "G.I. Jeff", which features Britta (Gillian Jacobs) and Abed (Danny Pudi) as their alter-egos Buzzkill and Fourth Wall, who explain to two kids why graffiti is wrong, while commenting on the nature of these messages as a whole. Take a look at this video, then read on for more details about the episode.

Executive producer Chris McKenna teased in our report from last week that the episode starts with G.I. Joe battling Cobra, before something happens that involves the Greendale study group, with a mystery that Jeff (Joel McHale) must get to the bottom of. Chris McKenna also revealed that "G.I. Jeff" is also a significant episode, in regards to Season 5 as a whole.
