I showed this one to people early, way back on February 27, during the last Ultimate Bot Tournament. Here is the conversation from RinkChat about it:

Sam: http://www.rinkworks.com/sneak_preview_one_niner.html
Revan: It's preview one-niner!
Randy: LOL LOL
Goosey: LOL LOL
Goosey: "Attack one at a time!"
MissyCat: LOL
Lirelyn: LOL
TalkingDog: Nice.
10Kan: LOL
Bryn: Hehe. Cool.
Randy: Love "I'm supposed to be on break"
Sam: hehehe
Sam: That's probably my favorite line in that one, too.
10Kan: "DISHARMONY!"
Lirelyn: I love the wicked cunning of "attack one at a time."
Brick: "Eeep!"
jaime: funny funny
Sam: You might (or not) be wondering why I chose comics 1, 5, and 19 to preview, as that's sort of random. Basically I was looking for ones that didn't give away the plot changes I'm doing. Those three seemed pretty self-contained.
Randy: I hope against all hope there are jokes about Sinbad throwing his sword away during every stupid fight.
Sam: Randy: Yes, but probably not what you're expecting.
Revan: It's looking really well-done. I can't wait for the webcomic to start already!

Additionally, I showed this to a friend of mine, who is a journalist. She replied: "I think I should suddenly shout 'DISHARMONY!' next week in one of the murder trials I'm [covering]. Or one day when it's suddenly quiet in the newsroom."
