HI, I'M RANDALL MUNROE, FOUNDER AND CEO OF XKCD. LAST NIGHT, AS I WAS RELAXING IN MY BALL PIT, DEBUGGING THE SUPER SOAKER FIRMWARE I AM DEVELOPING IN PYTHON, YOUR MOM HAPPENED TO PASS BY, LOOKING MYSTERIOUS AND QUIRKY. I CONSIDERED IT A GOOD OPPORTUNITY TO INTRODUCE HER TO MY THICK LINE. I SPREAD HER PARALLEL SEGMENTS WITH MY UPPER STICKS, THEN I TAPPED HER INTERSECTION WITH MY THICK LINE, AT FIRST SLOWLY, THEN I ACCELERATED LOGARITHMICALLY UNTIL MY THICK LINE PRODUCED THINNER LINES. OR AT LEAST, THAT'S WHAT SHE SAID. I GUARANTEE IT.
