The Sam and Max costume is the world's greatest lost treasure (proof), so it's great to see another glimpse of it via Skunkape's Twitter. Ex-Telltaler Nick Herman filmed this footage way back when and has recently been digitising his camcorder tapes.
The clip clearly shows now-Skunkaper Jake Rodkin trying the Sam head on, which leads us to believe he's a primary suspect in the disappearance of the suit. The legend says that once you wear the Sam head, it becomes tied to you forever.
Skunkape also shared a neat clip of David Nowlin recording Sam dialogue for Culture Shock. Thanks!
