Spanish

He's got no idea. I mean he's a fucking dog! How the hell would he understand spanish? does Murphy even translate to spanish? El Murpho, El Murphtino, El Murphesto? yeah, nevermind. Murphy translates to spanish just fine.

Adios, bitches.

why he can't sniff every dog butt that walks by.

Not much more to say. He wants to sniff all the dog's butts all the time. I mean he's a dog he wants to sniff a butt, chase something around in circles, be best friends forever. That's about it.

Money

Murphy doesn't understand money. He doesn't care about your economy or your stock portfolio. Murphy thinks your 401k is for boners because he can't make heads or tails of it because he is a goddamned hound dog. Does it smell like bacon? can he chase it? can he howl at it? No? then suck it and come back when it does.
Some jerk once tried to explain to Murphy that money was the root of evil. Murph didn't care because money makes no sense to him. Paper to get things? what? Plus, Murphy knows that the root of all evil is the heart of a black soul. A force that has lived all eternity.
Money? no. He's a dog, not queen of england.
