* EnsembleDarkhorse: Giorgio A. Tsoukalos. The new season even features him accompanying the History Channel's team. It's gotta be the [[EinsteinHair hair]].
* HilariousInHindsight: Catch a rerun of episodes where they ominously go on about [[MayanDoomsday the Mayan Calendar and December 21st, 2012]] and the people seriously intoning about how Something Will Happen.
* MemeticMutation: [[http://knowyourmeme.com/memes/ancient-aliens Giorgio Tsoukalos]] has spawned a popular image macro series mocking his theories about aliens. Must be the hair.
* {{Narm}}: Pretty much the whole reason to watch the show. A particularly memorable promo had this line from Tsoukalos:
--> '''Tsoulalos''': The Large Hadron Collider bears an uncanny resemblance to the Mayan Calender. Coincidence? ''I think not''.
* SnarkBait: See {{Narm}}.
