answer: #Person1# tells #Person2# a joke that three men were crossing the desert and they could only take one thing. The Englishman brought some water; the Scotsman brought a map, and the Irishman brought a car door to open when hot.
documents: #Person1#: Do you want to hear a funny joke?
  #Person2#: OK. Are you sure it's funny, though?
  #Person1#: Well, you'll see.
  #Person2#: OK.
  #Person1#: OK, an Englishman, a Scotsman, and an Irishman were going on a trip across the desert, and they could only take one thing with them.
  #Person2#: I see.
  #Person1#: So they met up at the start of the journey and showed each other their equipment.
  #Person2#: Oh, that's funny!
  #Person1#: Hang on, I haven't finished yet.
  #Person2#: Oh, sorry.
  #Person1#: Well, as I was saying, they showed each other what they had decided to bring. The Englishman had brought some water. ' If we get thirsty, we'll have something to drink, ' he said. The Scotsman brought a map. ' If we get lost, we'll be able to find our way. ' The Irishman had brought a car door.
  #Person2#: A car door? You mean just one car door?
  #Person1#: Yep. A car door. ' Why the door? ' the others asked him. ' Well, ' he said, ' If it gets hot, we can open the window. ' Do you get it?
  #Person2#: Well. . .
