Is the stadium full? nope. is there more than 20000? yup. nuf said. The original argument is posting a halftime pic says nothing. it still says nothing. Are TCU fans terrible? yep. did they inflate 40000? who knows I am not gonna count each dot but its safe to say its closer than what you are saying.
