*knock knock knock*
Brain: Hold on...hold on.  I'm coming, sheesh.  
*Brain opens door*
Body: Hey man...h-hey.  
Brain: Jesus, Body.  What time is it?
Body: It's nine at night, man.  
Brain: This is when I rest, Body, you know that.  What gives?
Body: I just, I just need a little bit of endorphin, man.  J-just a little bit.  
Brain: Ok ok, take it easy. What is he doing right now?
Body: Watching TV, man.  Come on, I just need a little.  
Brain: Listen, I'm not just gonna give you any endorphins without any stimuli. What is he watching?
Body:  60 Minutes.
*Brain goes to close the door*
Body: Ok ok, let's make a deal, man, ok?  Let's make a deal. OK, h-here's the deal.  You give me some endorphins now, and then I promise he'll go to the gym or something once he feels starts feelin it. Cool?
Brain: That's not how it works, Body.  You know that.  
Body: I know, b-but what do you want me to do?!  He just SITS there, watching 60 Minutes. I need those endorphins, man!  
Brain:  What about sex?  I can kick out some endorphins for that.
Body: Chicken and the egg, man.  
Brain: Well look, I don't give this stuff out for free.  Get his act together and come back later.
Body:  L-let's talk about this, man.  Let's talk about what I can do for you.  How about I walk to the library tomorrow, would you like that, man?
Brain:  Goodnight, Body.
Body: Listen, I- I didn't want to do to this...
Brain: Hey...HEY, what are you doing?
*breaks finger*
Brain: You f*cking psycho!  
Body:  GIVE ME THOSE ENDORPHINS!
Brain:  Alright fine, HERE!  Take your beloved endorphins, Jesus.  
Body: Ohhh, yeaaaah.  N-nice, man, nice.  Life is looking better already.
Brain: You know they don't last forever, right?
Body: Just, shh, man.  Let him enjoy this. 60 Minutes just got twice as exciting.
Brain:  Now go to the gym, Body.
Body:  Why would I go to the gym when I already have endorphins?
*Body sprints away as Brain sadly watches him go*
Brain:  Dammit, my finger.  I guess a few little endorphins can't hurt, right?
