Yesterday we caught our first look at 'Community's Greendale gang gloriously recreated as puppets for Thursday's all-new episode "Intro to Felt Surrogacy," along with confirmation that the out-there concept episode would once again feature the 'Community' stars breaking out into song. Now, yet another preview for the highly-anticipated episode has arrived, featuring our first look at 'Seinfeld' star Jason Alexander! But who is the mysterious mountain man?

'Community's Greendale gang will get the full puppet treatment for this Thursday's all-new episode "Intro to Felt Surrogacy," in a buzz-worth episode guest starring musician Sara Bareilles and former 'Seinfeld' star Jason Alexander.

Not only will Alexander's character reveal himself as a mountain-dweller living off the land, but also a former Greendale student! Could he be represent the future for the Greendale seven if they fail to graduate before the end of the season?
