Says who?  Try asking a biker if you can have sex with his thirteen year old daughter.  Try asking a cop if he is an asshole.  Try asking a teacher a question that’s clearly answered in the syllabus, on the very first page, in extra-large, highlighted bold text, and see if doesn’t change the teacher’s opinion of your academic ability.  “Now I ain’t tellin’ ya again.  You ask one more stupid question, and I’m breakin’ your kneecaps.”  And while we’re on the topic, yes, there are stupid questions.
