How do you explain that?

So there are some things that are just a little difficult to explain to a Malawian in a village. I've started a list.
riding lawn mower
ice skating
TV dinners
bread machine
treadmill
wieght machine
electric can openner
Easy Bake Oven
Lite Brite
obesity
diet self help books
Wal-Mart super center
maize fields in the plains
credit cards
a budget
a morgage
on-line dating
Toys R Us
the mall
halloween
milk/beef mega farms
wallpaper

If you've got some ideas of how to explain any of the above let me know :)
