Very ironic you bumped this one Kelly! After the last few weeks of school holidays I will confim that the age and sex of children at their silliest/stupidest is boys aged 15-17!!! And it's not all thought up in their own heads. With shows like Jackass, Wildboyz, The Dudesons, Viva La Bam, Dirty Sanchez, Trailer Park Boys and The Backpackers these boys have turned into dare devils with absoluely no brains! While my own son has tried and invented a few idiotic stunts, I've been amazed and appalled at some of the ones that these kids video on their camera phones and put on their myspace. What's worse is their mates keep filming the "stunt" after things have gone wrong!
