He’s not a yoga instructor, a yard salesman, disc jockey, clown teacher, shoe maker, or watch dog.  There’s an innumerable amount of things he’s NOT, but what he IS happens to be the chief medical officer of the USS Enterprise, Dr. Leonard McCoy.  RIP, old friend.

Lieutenant Commander Worf, the gentle Klingon.

Commander Charles (Trip) Tucker III from the much under-rated and short-lived Star Trek: Enterprise.  Coincidentally, this wasn’t the first Star Trek series to fall victim to an untimely cancellation.  See: Star Trek (1979)

“I have been and always shall be your friend.”

Mister Spock.

“Synthetic scotch, synthetic commanders..”

It’s Montgomery Scott, the real deal miracle worker chief engineer of the USS Enterprise!

”..N, C, C, 1, 7, 0, 1.  No bloody A, B, C, or D!”

“You’ve got the bridge, numba one!”

It’s Commander William Riker, second in command and chief of sexy beard-‘stache of the USS Enterprise D and E.

Bonus points if you can name this film:

Who wants a mustache ride?

Captain Jean Luc Picard of the USS Enterprise D and E.

"Engage."

Commander LaForge, chief engineer of the USS Enterprise D and E.  Host of Reading Rainbow.

Captain James T. Kirk of the USS Enterprise, flagship of Starfleet, representing the United Federation of Planets.

It’s the holographic doctor from Star Trek Voyager, appropriately named Doctor!  I always thought they should have called him Hal.  It could be short for something like Holography Assisted Life-form.
