Girl: Dad, I need a few supplies for school, and I was wondering if…

Dad: Yeah. There are a couple of pencils and an eraser in the kitchen drawer, I think.

Girl: Dad, I'm in eight grade now, and I need REAL supplies for my demanding classes.

Dad: Oh, so you need a ruler too?

Girl: Dad, I need some high-tech stuff like a calculator, a Palm Pilot, and a laptop computer.

Dad: Uh. I didn't have any of that when I was in middle school, and I did just fine.

Girl: Yeah, and they weren't any cars either, were there? And things are just more progressive now.

Dad: Well, we can rule out the hand pilot.

Girl: Palm Pilot, Dad.

Dad: Whatever, and the computer . . . unless mom lets you sell the car. And as for the adding machine…

Girl: Calculator.

Dad: Yeah, I think mine from college is kicking around here somewhere.

Girl: Dad, I need a calculator for geometry, and I have heard you can download free software from the Internet.

Dad: Great. My daughter will be playing video games in geometry class.

Girl: Dad…

Dad: Okay. How much is this thing going to cost me?

Girl: Well, I saw it at the store for only $99, with a $10 mail-in rebate, or you could buy it online.

Dad: Oh. Do they throw in a few aspirin so your father can recover from sticker shock?

Girl: Dad. Please!!! Everyone has one and you always say you want me to excel in school, and I'll chip in $10 of my own, and I'll even clean up my room.

Dad: Hmmm, 100 bucks. Well, you'll be supporting me in my old age, so, I guess so. When do you need it?

Girl: Now, right now. Mom's already waiting in the car for us. She said she would buy me an ice cream if I could talk you into to buying it for me today.
