YMMV: Ancient Aliens
- Ensemble Darkhorse: Giorgio A. Tsoukalos. The new season even features him accompanying the History Channel's team. It's gotta be the hair.
- Hilarious in Hindsight: Catch a rerun of episodes where they ominously go on about the Mayan Calendar and December 21st, 2012 and the people seriously intoning about how Something Will Happen.
- Memetic Hair: 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 emphasizes his style of logic (or lack thereof).
- Memetic Mutation: 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:
Tsoukalos: The Large Hadron Collider bears an uncanny resemblance to the Mayan Calender. Coincidence? I think not.
- Seasonal Rot: 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.
- Snark Bait: See Narm.
- So Bad, It's Good: What else could a show that makes Sunn Classic Pictures documentaries look sober and reasonable be?
- Unfortunate Implications: 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 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 It's not hugely far-removed from the 19th century theories that Great Zimbabwe was built by "southern Jews".
