Archaeologist

As a time traveller, the Tenth Doctor told River Song that he "point[ed] and laugh[ed]" at archaeologists. (TV: Silence in the Library) River, who was herself an archaeologist, claimed that "an archaeologist [was] just a thief with patience" (TV: The Husbands of River Song) and said that, depending on when she arrived, she was either an archaeologist or anthropologist.
