It never ceases to amaze me to see just how stupid some people can be. We've got a prime example of this here where a British student queuing in Miamai Airport for a plane home thought it would be a laugh when asked what her rucksack contained, to reply "...be careful, I have three bombs in here"!
Unsurprisingly, the US authorities were less than amused about this, and Ms Student is now in the pokey. Could I suggest that she remain incarcerated until safely past the age of child-bearing, thus cleaning up the human gene-pool a little.
Incidentally, what was she studying - advanced stupidity, perhaps?
