“If there are no stupid questions, then what kind of questions do stupid people ask? Do they get smart just in time to ask questions?”

“Why?' is always the most difficult question to answer. You know where you are when someone asks you 'What's the time?' or 'When was the battle of 1066?' or 'How do these seatbelts work that go tight when you slam the brakes on, Daddy?' The answers are easy and are, respectively, 'Seven-thirty in the evening,' 'Ten-fifteen in the morning,' and 'Don't ask stupid questions.”

“There is no such thing as a stupid question. Just stupid people who ask questions.”

“Dogbert to Dilbert"My invention can detect human stupidity. It has a very simple interface. All I do is point it at people." "Then what does it do?" "Why would it need to do anything else?”

“Every other question has an answer to why. Onlyprobability is inexplicable.”

“The only stupid question is the question that is never asked.”

“It's the stupid questions that have some of the most surprising and interesting answers. Most people never think to ask the stupid questions.”
