Sheldon Cooper's Mortal Enemies List

Sheldon Cooper has been maintaining a list of "mortal enemies" since 1989. By 2011, Sheldon's list had grown to 61 people.

The list was originally stored on a five and a quarter inch floppy. When the floppy disk failed in 2011, the person in charge of quality control at the Verbatim Corporation was added to the list.

According to Howard in The Tam Turbulence, Sheldon's list of mortal enemies is available online with an updated interface that allows searching by first name, last name or length of grudge.

People featured on the list:

  • Joel Schumacher, who nearly destroyed the Batman franchise. [The Creepy Candy Coating Corollary]
  • Wil Wheaton, who failed to show up at the 1995 Dixie-Trek convention in Jackson, Mississippi. Sheldon traveled ten hours by bus to reach the convention and ask for Wil Wheaton's autograph. Wil was first removed from the list in 2011. [The Creepy Candy Coating Corollary]
  • Billy Sparks, Sheldon's childhood neighbor, for putting dog poop on the handles of his bicycle. [The Creepy Candy Coating Corollary]
  • The person in charge of quality control at the verbatim Corporation in 1989. [The Russian Rocket Reaction]
  • Star Trek: The Next Generation's Brent Spiner was added to the list after he ripped open a mint-in-package Wesley Crusher collectible that Wil Wheaton had just signed and given to Sheldon. [The Russian Rocket Reaction]
  • Wil Wheaton was added back to Sheldon's mortal enemies list in 2017 when he landed the role of Professor Proton in a new edition of the show. Wil was once again removed from the list in The Novelization Correlation, when Sheldon finally watched the new Professor Proton show. [The Proton Regeneration, The Novelization Correlation]
  • Tam Nguyen, Sheldon's childhood best-friend. When he visited Pasadena and reached out to Sheldon, Tam didn't understand what he had done to upset Sheldon. Sheldon eventually explained that he felt betrayed by Tam when he didn't move out to California with him, as promised, and instead stayed in Texas with his girlfriend. Sheldon forgave Tam, who pointed out that their lives both worked out well anyway. [The Tam Turbulence]
  • Jim Henson, for "putting a terrifying, giant yellow bird on television and in my nightmares." [The Tam Turbulence]
  • The university cafeteria ladies were on the list until they told Sheldon what's in the chili. [The Tam Turbulence]

On Young Sheldon

In the Young Sheldon episode "A Computer, a Plastic Pony, and a Case of Beer", Sheldon first created his mortal enemies list using a Tandy 1000 SL home computer at the local RadioShack store.

The document contained an alphabetised list of people who had wronged him and their crime:

  • Billy Sparks: Threw his chicken at me.
  • Dr. Karl Eberland: Clumsy tetanus shot.
  • Dr. Ronald Hodges: Pompous NASA scientist.
  • Georgie Cooper: Passed wind on my head.
  • Matilda Sparks: Mean chicken.
