The most intelligent/maniacal/deviant one-year-old you will ever see in your life, and clearly the best character on Family Guy. Seth MacFarlane is such a damn genius.
"So, is there any tread left on the tires? Or at this point would it be like throwing a hot dog down a hallway?"

Stewie is a bad-ass muthaf****. Don't mess with the best.

You can find him in vents mostly in New York City. Especially if the vent is bent and you can smell eggs. He likes to hide under beds and possess people. Stewie likes to jump out of windows without screens and scream "What what in the butt". You can find him hanging out with churros. New York would not be complete without Stewie. he can come to life if you write a fanfic about him.
Person 1: Why is our vent bent????
Person 2: RUN FOR YOUR LIFE AND GRAB A CHURRO BECAUSE STEWIE IS COMING SHAWTY GIRL
