[A rhythmic morse code of nom, nom. Nom nom nom. Mmmmnnnuu. Nom ... Followed by miniature elephant sounds and a series of monkey squaks.]
Allow me to interpret.
Lucas: Dude. You are soooooo needy. Mom can't even open her computer without you being strapped to her chest in that kangaroo pouch thingy.
Benjamin: Whatevs. You have casts.
Lucas: That's what you got for me? That's all you can come up with?? So lame. Clearly, we can see who is the dominant personality here.
Benjamin: What's with your elephant noises anyway?
Lucas: I don't need to dignify that. And it's totally your fault that mom had to give up the nursing. Those were some nice ta tas.
Benjamin: I've had better.
Lucas: I will cut you, boy.
That's when I walked in to stop the argument only to find them like this. Quite the feisty bunch.
