The other day I went to Office Max to get some supplies. While there I bought a new ink cartridge for my printer. It came in a fairly large box mounted on a card and wrapped in plastic.
When I took it apart, which took an unnecessarily long time, I found that the printer cartridge itself was actually quite small. It seems they made the packaging large to make it harder to steal and to make the customer feel better about the high price.
So I pointed this out to my wife and mentioned how my weight gain over the years of our marriage should have the same effect... It made me seem more valuable and also made me harder for other women to steal. She's still laughing.
