Isaac: What's he saying?
Dana: It's tough to tell – he’s laughing pretty hard. Now he's telling his friends. And there, he just hung up.
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 they often looks like they are 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.

When one of the subjects, not playing along, insists on asking when they can contact the authorities and her parents, he laughs and says she gets full marks for persistence. His assistant Dr. Skinner is less sanguine and tends to give the girls a contemptuous laugh as they insist that they can't do this.
- Ravensong: From Chapter Fifteen: When Stacey asks her Momma's name, due to a His Name Really Is "Barkeep" situation:

"Momma is my name." She laughed so hard the words were hardly intelligible. She recovered enough to finish. "It was the first word your Gramma learned. She thought it was a name. Imagine having Momma for a name." Both broke into hysterics. "If I'd stayed in school, them nuns would have changed it."

Giardella: Laura, Laura, I'm trying to tell you how high it is a value I place on our relationship. I'm trying to signify something to you here.
Laura: Will you excuse me for a moment?
Giardella: Yeah, sure. Do you gotta go to the bathroom or something? Yeah, you know where it is. Yeah, it's right over there. Just help yourself.
[Laura enters the bathroom]
Laura: [silently laughing] Oh, my God.
Giardella: [through the door] Yeah, you know, and if I come back, uh, we could drive wherever, you know. Maybe one of them, uh, breakfast and board places in them quaint areas. You know, one of them places with the quilts on the bed and, uh, those pictures of the whaling guys. One of these days, all this bouncing around like a cue ball is gonna stop. I'm gonna get myself set up somewhere. Out west, maybe. Can you hear me, Laura? You fall in in there?
- Played for Drama in the Star Trek: The Next Generation Series Finale, "All Good Things..." — Picard (and the audience) do not understand why Q finds his question laughable:

Q: Yes. You're doing it right now. You did it before, and you'll do it yet again.
Picard: What kind of meaningless doubletalk is this?
[The whole courtroom laughs]
