Vegetable
"Thank you, Mrs. Sarek," McCoy said as Amanda set a plate before him.
"Please, Leonard, call me Amanda. Don't make me tell you again."
McCoy smiled. "Yes, ma'am." As she left the room, McCoy stared down at his plate. "Spock, what is this stuff?"
"It is a Vulcan delicacy, Doctor. It is fortunate your visit coincided with the seasonal availability of these vegetables."
McCoy frowned. On leave, he usually reveled in fried chicken and mint juleps. Neither was available on Vulcan, so with a sigh he lifted his fork and took a bite. The reaction was instant and violent. McCoy coughed and sputtered and blindly fumbled for his glass of water.
Veracity
"I am not questioning your veracity, ensign," Spock said. "As an ancestor of mine once said, when you have eliminated the impossible, whatever remains, however improbable, must be the truth."
"You're saying Sherlock Holmes was your ancestor?"
"The phrase became common on Earth after it was used by Sir Arthur Conan Doyle. It has existed on Vulcan since the time of Surak."
"Sure, Mr. Spock," the ensign said, voice dripping with sarcasm.
"Do you doubt my word, ensign?"
"I'm just saying that's a little unlikely."
"Unlikely, yes, however not impossible."
