All right, even though Nerys Myk beat me to the punch, here's some old Photoshoppery back in the day when I actually had the time to do it:
Balok: "Hey, baby, let's go back to my place so we can drink tranya until our head's explode."
In order to be more environmentally friendly, contestants in the caption contest now take public transportation.
Same rules apply; best caption or insane Photoshopping (an example of the second one from 2008 can be seen on the first page) gets a win. Good luck, because you're going to need it.
Kirk: "It's a dummy. An anatomically correct dummy, but a dummy nonetheless."
Balok's puppet: "I have feelings too, you know."
Kirk: "What happened to that creepy old guy?"
Cloud William: "Cloud Festus in next cell with one with pointy ears."
Spock: "JIM, GET ME THE HELL OUT OF HERE!"
