A two-panel meme featuring characters Bernard Lowe and Theresa Cullen from the show Westworld. In the top panel, Theresa hands Bernard a document labeled "SKILL FILES". In the bottom panel, a close-up shows Bernard looking at the document with a blank expression, captioned: "CLAUDE: DOESN'T LOOK LIKE ANYTHING TO ME".
