The pilot goes "We're going down!"
The other pilot yells "Down like your syndrome?"
Listen up, nimrod. The joke is that one pilot says the plane is crashing, and the other one makes a dumb joke comparing it to Down syndrome. It's supposed to be funny because it's mean, but it's really just lazy and not clever. People with Down syndrome are like, twice as smart as you, so maybe you should stop laughing.
