Basic Trope: An archaeologist goes on globe-trotting adventures, essentially using his/her profession as an Excuse Plot.
Straight: Dr. Bob often goes on adventures in exotic locations and ancient catacombs in search of rare treasures while avoiding bad guys who are after the same items. Sometimes, he is shown giving lectures and doing museum work.
Exaggerated: Dr. Bob defends the galaxy from invading aliens, often spending days, if not, weeks on other worlds. His profession rarely comes up.
Downplayed: Dr. Bob spends a great deal of time at the university. If he gets involved in any adventures, they happen at the excavation sites where he is working.
Bob is part of the Masquerade which secretly protects rare, mystical artifacts from evil oculists. Archeology is just a front.
Bob is at an excavation site that's genuinely difficult or dangerous. He'd be dead if he couldn't handle himself in a fight or disaster.
Inverted: Officer Bob ignores crime-fighting in order to study archeology.
Subverted: Dr. Bob tries his best to do his job and tries not to go on treasure-hunting adventures.
Double Subverted: But when one of his students goes on an adventure to recover a lost treasure from Somali pirates, Bob has no choice but to follow along to protect him.
Parodied: Dr. Bob is Archeology Man, a costumed superhero who fights crime using historical facts.
Zig Zagged: Dr. Bob is an adventurer who loves history but finds office working to be boring. When his superiors put pressure on him, he comes back to work but soon quits it altogether to become a fulltime adventurer. He makes a living by stealing the treasures he finds.
Averted: Dr. Bob is just an archaeologists who does everything any other archaeologist does and hardly leaves his hometown.
Enforced: The writers want a reason to send Bob to exciting locations and uncover ancient, mystical relics. Archeology seemed like an appropriate excuse.
Lampshaded: "Who knew that a career in archeology would be so dangerous."
Invoked: Dr. Bob is an adventure seeker and got into archeology as an excuse to go to dangerous locations around the world for the sheer thrill of it.
Defied: Dr. Bob has the opportunity to go on adventures but refuses, preferring to stay at the university and teach.
Discussed: "Where's Dr. Bob? I bet he's on another one of his adventures, isn't he?"
Conversed: "This show is great but you have to wonder how Bob manages to stay employed when he is getting into trouble halfway across the globe every week."
Implied: "My grandfather was an archaeologist. Never saw the inside of a museum, though. Too busy traveling the world and trying not to get killed."
Deconstructed: Dr. Bob goes on adventures and never attends his own lectures. This gets him in trouble with the Board of Education who fire him.
Reconstructed: He is rehired, however, when his adventures begin to uncover huge findings in archeology. Because of this, he is seen as a sort of Bunny-Ears Lawyer.
Played For Laughs: While Bob is off fighting bad guys in another country, a Running Gag involves his students patiently waiting for his lecture to start, spending an entire month in an empty lecture hall.
Played For Drama: Bob cares enough about preserving history that he is willing to go to dangerous locations and brave the elements/wild/locals in order to do it.
