Step brothers.
"When I was a kid, when I was a little boy, I always wanted to be a dinosaur, I wanted to be a Tyrannosaurus Rex more than anything in the world, I made my arms short and I roamed the back yard, I chased the neighborhood cats, I growled and I roared, everybody knew me and was afraid of me, and one day my dad said "Bobby you are 17, it's time to throw childish things aside" and I said "OK Pop", but he didn't really say that he said that "Stop being a fucking dinosaur and get a job".
Best film ever 10/10.
