Since it's personal opinion, what is your idea of a stupid question, besides this one, not just on GAG but in general?

[Extraterrestrial1999]

One where the answer should be obvious to the person asking

One that's random or not revelant to anything in the moment

One that is hard/impossible for people to answer

All three fit the criteria

I don't believe there is a such thing as a stupid question

I tell my students that the only stupid question is the one you do not ask.

[jahaims]

Ones that can be answered with either deductive reasoning or critical thinking.

All three fit the criteria

Irrelevancy is my bear. Drives me nuts

There are no bad questions, just bad askers.
