Cool list of MacGuffins in film and TV

This is neat. A list of MacGuffin examples from various films and TV shows.
What’s a MacGuffin/McGuffin, you ask? Well … It’s something really important…
A MacGuffin (sometimes McGuffin or Maguffin) is a plot device that motivates the characters and advances the story, particularly one whose importance is accepted completely by the story’s characters, yet from the audience’s perspective it might be minimally explained or may test their suspension of disbelief if it is scrutinized. The device, usually an object, is common in films, especially thrillers.
