Raylan Givens (Timothy Olyphant) mentions Vanderbilt University. The university was named in honor of Cornelius Vanderbilt, Olyphant's great-great-great-great grandfather.
When speaking to Raylan about prison guard Ash Murphy, Boyd Crowder refers to him as a "bent screw". Screw is prison slang for prison guards and by calling him a bent screw, Boyd is telling him that Ash is corrupt.
