Knock-Knock Spock

This is a remake of the comic strip that started it all, "Knock-Knock Spock"

I made a few changes;

McCoy's mischief is made more clear by his expressions.
Spock is less relaxed, more... Vulcan.
The computer called Spock "Commander" in this version. I thought it was more fitting for the situation.
The panel with McCoy's punchline was made separate in this version to give more emphasis on McCoy's malicious intent.
I had fun with Spock's expression here. Using traditional absurd cartoon elements, I made his eyes into water faucets.
