input: Please answer the following: W: Well, it was my trip in Nepal. We went there 10 years ago, doing some walking in the mountains. M: How long did you stay there? W: 20 days. M: 20 days! That's a long time. How far did you walk every day? W: Perhaps 15 kilometers. You have to climb up and down a lot every day. M: So, it was very hard. W: Yes, very hard. Sometimes, it's difficult to walk in the mountains where the air is very thin, and you have a lot of problems when breathing. M: What kind of equipment did you take? W: Not much. Only a bag, a sleeping bag and some warm clothing. We carried all the things by ourselves. M: And how was the food? W: There was rice and some vegetables, normally no meat. But it was good. M: What was the best thing about the trip? W: The walking and the exercise. I hate sitting in the sun and like to be out in the countryside. The air is very clean and it's very quiet. Nepal is a good place. You must go! What was said before this conversation?

They call him the "Grip" for short. Heather: Who in the world is he? John: You've never heard of him? [No.] He's the world famous snake trainer ... He's never met a snake he couldn't train to dance and hiss at the same time. Heather: Seriously? Where is he? John: Uh, he's the tall guy over there in the purple jacket and green pants. He probably has a snake or two with him tonight. Heather: Huh? John: And then there is Georgina, the Great. Heather: Georgina ... and great for what? John: Are you serious? You've never heard of her? She is the world's greatest arm wrestler. I mean, World champion. She's the petite woman next to the fireplace with the bright yellow dress and the tennis shoes. Heather: I thought you said famous people ... like, like people we all know. John: And, and there is Brad Pitt ... Heather: Now, there's someone I recognize ... John: ... the captain of the national Yo-Yo team [What?]. Yeah. He's the short, stocky man sitting at the table wearing the black and red checkered shirt.
