So? why is this so funny?

I have a chance to buy 72 hour kit food in mylar bags. I got 6 of these in early 2008 and figures it's time to rotate out the old. We pulled out the old packs and the two boys can not stop laughing about it. We decided to try a day of eating the rations, just to see if it is enough. For some reason this idea was insanely funny. Joseph is relieved that there are 4 pieces of candy per day for a snack. The boys were able to pack one days worth of food in a sandwich sized baggie. Ya, that was funny too, oddly. I'll let you know what is decided on the experiment.
