If there were two of me, I would like to think it would be twice the sarcasm.
Let’s see. Two of me. Twice the… flirting? Twice the silliness? I just don’t know.
I’d like to think that I’d be able to help more friends when they’re having problems, rather than having to divide my time between them.
The monstres would rise up, overthrow the humans, and rule the world!
MUHAHAHAHAHAHAHA!!!
Surely you jest.
I have more time to nap, therefore I would be far less bitchy.
Well, the chatters would certainly benefit. Unless, of course, all of them have me on /ignore by now…
If I were cloned?
EGADS, I don’t think there would be many benefits in that. Hell, I wont even have children let alone allow me to be cloned, there would be something seriously wrong. I think the world would tilt on it’s axis if I were cloned.
Double your pleasure, double your fun…
oh, who am I kidding.
If there were two of me, I’d become a lesbian. 
There would be one more editing, proofreading “cop” running around correcting public signs with a pen–except I’d be able to cover twice as much area as I do now.
I’d/We’d be wearing out the slot machines in Vegas twice as fast.
Trek geekery would increase (as if the world needs any more).
If there were two of me, I think the universe might collapse.
Overestimating my importance? Well yes, but there would be twice as much overestimating of my importance! 
There’d be twice as much sweet, sweet grendel lovin’ to go around…
Or not.
World not big enough for two astros. War of titans ensues. Major cities destroyed by astro’s radioactive breath while astroclone’s giant tail and “mad chicken” dance crushes several downtown shopping centers. Eventually earth is destroyed, because a certain puckish little woman with red hair just couldn’t leave well enough alone.
Crickets would riot from working overtime.
Well considering I wouldn’t stop with just 1 clone the world would have to face the largest most apathetic army ever envisioned by man.
Interesting question…Unfortunately, I am a clone (I’m an identical twin), and IMO my doppleganger has turned evil. In any event, my wish would be to not have an identical jackass around…
If there was a clone of me made today, it would be 14 years before it could post on the board on how it could improve the world 
Well, I’d benefit, because my clone would be the slave clone, doing all the chores and crap jobs. So then I would be freed up to enjoy life and spread sunshine and rose petals hither, thither and yon! That can only make the world a better place, right? Can’t have too many rose petals!
R.J Reynolds and Budweiser would make more money.
Another red-headed Italian? What’s not to benefit?
And with three kids, a part-time job, two dogs and five cats, frankly, I could really use the back up
24/7 hardcore bad-ass MPSIMS-moderating.
I would finally have an excuse for my double-posts!
