McCoy: Hiccups, eh? You know, come to think of it, I don’t think I’ve ever caught him hiccupin’ before…
Spock: Vulcans are as equally prone to hiccups as humans are.
McCoy: I suppose your “superior” Vulcan biology allows you to control them better?
Spock: On the contrary, Doctor. Vulcans are merely less prone to partake in the causes of hiccups such as consuming carbonated or alcoholic beverages, or suffering from emotional stress or excitement.
McCoy: No emotional stress or excitement, eh? *leans closer to Spock, refusing to blink or break the eye contact*
Spock: *stiffens posture* What are you doing, Doctor?
McCoy: *moves a bit closer, grinning* Don’t mind me, Mr. Spock.
Spock: That is becoming increasingly difficult, given you are enclosing on my personal space rather quickly.
McCoy: *stills* Oh. Is my closeness bothering you?
Spock: *flushes slightly* I did not state that it did.
McCoy: Then you’ll have no problem with this, right? *Pecks Spock’s cheek with a kiss*
Spock: *inahales sharply in surprise* Doctor, I- *flinches*
McCoy: Spock? *moves away a bit* What’s wrong?
Spock: *hesitates* I think that-HIC
McCoy: …You’re kidding me. *grins*
Spock: This is not hu-HIC-merous, Leonard.
McCoy: *bursts out laughing* Oh my god! You’ve actually got the hiccups! I gotta show Jim this! *rushes out the door*
Spock: *calling after him* Leonard, do not-HIC-involve the -HIC-Captain!
