Scott: Dave. I'm going to the supermarket to pick up food and drink for Saturday's picnic later. Any suggestions? Dave: Well, everyone has been talking about having a barbecue down by the river, so why don't you pick up some hamburger and hot dogs? Scott: Okay, but how much hamburger meat are we going to need? And hot dogs too? Dave: Uh, I don't know. How about three pounds of hamburger and a couple packages of hot dogs? Scott: Oh, that's not going to be enough. Do you remember the last picnic we went on? Your roommate, Jim, ate about ten hamburgers by himself! Dave: You're right. Let's see. I'd better write this down. Uh, let's see about nine pounds of hamburger meat and, uh ..., seven packages of hot dogs. Scott: And you better pick up some chicken for those who don't like hamburger or hot dogs. Dave: Okay. How about five or six bags of potato chips? Scott: Humm. Better make that eight or so. Dave: Alright. Oh, and we're gonna [going to] need some hamburger and hot dog buns. How about five packages a piece? I think that sounds about right. Scott: Yeah, you better pick up some mustard, catchup, and mayonnaise too. Dave: Okay. What else? Uh, we're gonna [going to] need some soft drinks. How about ten of those big 2-liter bottles? Scott: Sounds fine, but be sure to buy a variety of drinks. Dave: Okay. And what about dessert? Scott: Well, maybe we could ask Kathy to make a few cherry pies like she did last time. Dave: Well, I wouldn't mind that, but you know, she's been very busy working two jobs, so I'd hate to ask her, [Oh, hum ... ] and uh ... Hey, why don't you whip up some of your oatmeal cookies? [Well ...] Hey, you could even ask, uh ..., what's her name ... yeah that new girl, Susan, the one that moved in across the street! [Well ...] I bet she'd be willing to help you! [I don't know ... ] She's a real knockout! Scott: Nah, I don't think I could ask her ...[Ahh!] I don't know her phone number, plus ... [ Door bell rings ... ] Dave: Hey, you don't need to. She's at the door! Scott: What do you mean? Dave: Well, I thought you two would hit it off, so I called her up saying I was you, and I invited her over to watch a movie. Scott: You did what??? Dave: Wait, wait, wait ... [uhhhhh ... ]
