If I were stranded on a deserted island, with plenty of food to eat and water to drink, the four things I'd most like to have with me would be:
(I'm skipping answers like "a yacht" or "a cellphone," which aren't really in the spirit of the question!)
1. Lauren and Charlie (as "my family," this counts as one thing -- I made the Blog Idea of the Day, my rules!)
2. A TiVo and Sattelite-Equipped television
3. A great pillow
4. An endless supply of multi-ply toilet paper.
