It had been extremely difficult for Jim Kirk to admit to his friend and doctor, Leonard McCoy, how he'd broken his arm in the shower.
“You expect me to believe that you broke your arm because you were in the shower with Spock?” McCoy asked with a shake of his head. “That’s a cock and bull story.”
“Only half of your statement is correct doctor,” Spock piped in. “There were no male bovine animals present.”
McCoy sputtered incoherently and stopped questioning Jim, opting to mend his arm in silence instead.
