Bart wasn't far behind at all. As a matter of fact, upon closer inspection, Billy would see that one of the guys who was playing the new street fighter game had shaggy, long-ish red hair that stuck up like a mushroom cloud around him, suspended by static. Said boy also had huge feet.
Having inherited his grandfather's chronic tardiness, it was a rare occasion when Bart showed up anywhere on time, let alone early, but this was Street Fighter. Sacrifices had to be made for the greater good, and also for Bart to get his HADOUKEN fix (a word which he proceeded to yell every time he used that move).
