The Sulky Boys
From the animated TV series All Grown Up (11/29/2003). Another BBB (boring boy band) featured briefly in the "Tweenage Tycoons" episode of this Rugrats spinoff. The foursome charge $100 per ticket, so the grown-up Rugrats invent fishbowl belts to make the money. The Sulky Boys, who wear shirts that spell out SULK across their backs, are bland, inoffensive, and onscreen for a couple of seconds. Just long enough to merit a Rocklopedia Fakebandica entry, but not long enough to merit a very good entry.
