Touch (TV series)
Professor Arthur Teller (portrayed by Danny Glover) is an expert on children who possess special gifts when it comes to numbers. He runs the Teller Institute (seemingly a one-man operation out of his home) which specializes in misdiagnosed mutism in children. He seems very abrasive when he first answers his front door, but his tone quickly changes when he realizes he's found another gifted child. Showing his familiarity with similar situations, Teller makes a guess about Jake's cell phone tower incidents without prior knowledge.
