Parsifal: Do you want to hear a funny joke? 
Irishman: OK. Are you sure it's funny, though? 
Parsifal: Well, you'll see. 
Irishman: OK. 
Parsifal: 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. 
Irishman: I see. 
Parsifal: So they met up at the start of the journey and showed each other their equipment. 
Irishman: Oh, that's funny! 
Parsifal: Hang on, I haven't finished yet. 
Irishman: Oh, sorry. 
Parsifal: 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. 
Irishman: A car door? You mean just one car door? 
Parsifal: 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? 
Irishman: Well... 
Parsifal tells Irishman a cold joke about an Englishman, a Scotsman, and an Irishman taking some water, a map, and a car door on a trip across the desert.
