* 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.
* MemeticHair: The only reason Mr. Tsoukalos sticks out and gets made fun of the most is because of his hair. It's just so big, messy, and crazy. It really empathizes his [[InsaneTrollLogic style of logic (or lack there of)]].
* 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''.
* SeasonalRot: Not that the show is generally considered high quality to begin with, but the later seasons have essentially just repeated things already done in previous episodes or have to reach further and further to connect aliens with absolutely ''anything.'' To the point that one episode was a thin excuse to discuss superheroes because they were based on archetypes that might have been inspired by aliens.
* SnarkBait: See {{Narm}}.
* SoBadItsGood: What else could a show that makes Sunn Classic Pictures documentaries look sober and reasonable be?
* UnfortunateImplications: When one strips away the various pieces of ''flat-out wrong'' information produced on the show, it can fall into this: a great deal of the "alien" artifacts or human sites built "with alien assistance" are from pre-Columbian civilizations or sub-Saharan Africa, the implication being that these civilizations were [[http://drmsh.com/2014/07/05/the-racism-of-the-ancient-astronaut-theory/ too backward or stupid to create such impressive structures.]] For instance, the show once claimed that Puma Punku, a fifth century Aymara site in the Bolivian Andes, was "the only site created directly by extra-terrestrials". At the same time as Puma Punku was constructed, the Romans were building equally-if-not-more advanced stone structures...but ''of course'' those stupid Amerindians couldn't build anything white people could, they ''must'' have been helped by aliens![[note]]On the other hand, the show erroneously claimed Puma Punku was a couple of thousand years older than it is, so there's that.[[/note]] It's not hugely far-removed from the 19th century theories that Great Zimbabwe was built by "southern Jews".
