Rockets fans are notoriously some of the worst in the league. They rarely make noise unless prompted. And they are probably some of the least knowledgeable fans out there.
Of course some of that is because they are fat, lazy Texans who spend 90% of their free time saddled up to the counter at Dunkin Donuts or Krispy Kreme.
Most of them couldn't tell you what a three second violation is, but all of them can tell you what varieties of donuts are available at a given Dunkin Donuts in the greater Houston area at any particular time.
