Again, it's good news that a 6 year old child was not whipped through the air in a makeshift spaceship balloon but I'm inclined to agree here with the Nid Hog. Wife Swap not only once? I'm going with publicity stunt; another 15 minutes of fame for the amateur scientist.
Jeez, make me feel worse for buying into it. Note to self: don't watch non-national emergency news stories when sleep-deprived!
On that note, good night all!
