"Staaaar Trekkinn, across the Universe! Under the command, of our captain Kirk"
Well, assuming I'm on a Federation planet it would be wonderful because I'd never have to work a single day with all those replicators they have.... But there would be constant fear of the Borg eventually invading my planet and turning me into a mindless drone... less yay...
And depending what time period I would be in there would also be the potential threats of Klingons, Romulans, Dominion and so on and so forth attacking...
Or for my second choice that comes to mind, I'd just go around doing things that wouldn't normally happen in a children's cartoons such as excessive swearing and murders to see if the Universe would just collapse in on it's self, if it doesn't, then I just over throw the the racist egotistical tyrant Celestia riding into battle on a Dragon.
