Bones: "Spock knows."
Kirk: "That's right Bones. Spock?"
Spock: "Perhaps you should ask the Rolling Stones, Captain. "
Kirk: "What?"
Bones: "They're dead, Jim. Spock is just stalling because he doesn't know."
Kirk: "Spock?"
Spock: "Isn't Keith Richards still alive, doctor?"
Bones: "Oh yeah. That's right Spock. He was declared immortal late in the 21st century. It was fortuitous that time was on his side."
Keith Richards:
"Currently there is no established unit of time smaller than the Planck time, which is approximately 5.4 x 10^-44 seconds. At scales smaller than the Planck time, our current physical theories fail to provide meaningful descriptions of reality. "
Bones: "Keith, how did you figure that out?"
Keith Richards: "Mushrooms, mate."
Spock: "He must be a vegetarian."
Kirk: "I'll explain it later, Spock."
Sir Brian May: "Are you guys sure about that? Just wondering."
Keith Richards: "Astrophysicists. Bloody hell."
