The truth is that there are, in fact, stupid questions. Sometimes, a question has such a blatant answer that the person who answers, usually a Deadpan Snarker, can't just say yes or no, or give any normal answer. Instead, that person completely cracks up, to the point where he or she often looks like he or she is giving the phrase a new meaning. When this scene occurs, it is a Literally Laughable Question. If the person laughs for an extremely long time, it is also an Overly Long Gag.
While this sometimes occurs in real life, it is usually used in fictional media as a comedy trope.
