Also a velociraptor. Apparently velociraptors are potato-shaped.
'allo. 
(I’d never heard of an allosaurus, and now I are one)
Me, too, even though I said I’d prefer small crowds.
Rowrr!
Edmontosaurus. The prehistoric cow apparently.
Another allosaurus. Can I join the gang?
Have you got a leather jacket?
T-Rex here, which I suppose works with my giant head and stubby arms.
I’m a velociraptor.
But I want peace with the XKCD guy.
No.
::hangs head and shuffles off, dragging tail::
Me too here. And it has cool stuff to make the roar sound acoustically trumpet-like, which is awesome. I might have to look into replicating that…
Whooops! The file’s not there any more, it’s here.
That is so cool! I think I might have a new favorite. And I know I can find a doll and adjust it so it makes that noise. Yes, I am a loser. Thanks!
Allosaurus here. I mock all you T. rexes. Watch as I scratch those hard-to-reach places! Marvel at my three fingers on each hand! And all the cool kids know the Jurassic was the most happening time of the Mesozoic. Have fun when the asteroid falls on your collective heads!
I’m a T. Rex, and I’ve got the t-rex arms, too…
Just find somebody wearing one and eat them. Come on baby,look at those fangs. Do you really think you were meant to eat berries?
::CHOMP::
I’m a velociraptor.
Why couldn’t I have been an Archaeopteryx?
It seems we will be dividing into three groups. T. Rex, Velociraptor, and the mighty and certainly quite sexy Allosaursseseseses. Then we will eat our neighbors.
I am an apatosaurus. I think they typecast me because I’m fat. 
Not *all * of them. As a small-armed T Rex, who (as **Tuckerfan ** points out) cannot reach his weenie, I still say we should keep a couple of long-necked dinosaurs around for entertainment. Hey, pbbth, come over here!
