Episode title is a play on the song Johnny B. Goode by Chuck Berry.
As Dutch coughs up liar's blood, Herlin says she only has about 10 pints of that. A person's blood volume is directly proportional to their body size and mass. A 5 foot 7 inch, 120 pound woman has less than 8 pints of blood. Herlin would have about 11 pints.
