JESSICA shouts "whore" at pretty women, Michelle has uncontrollable violent body movements and Ben can't stop himself sniffing and shrugging, even in his sleep.

From the opening credits, it was obvious last night's Teenage Tourette's Camp (ITV) was classic viewing.

And not since the 1980s cult documentary John's Not Mad' has the disorder been so well documented.

The programme followed five teenage Tourette's sufferers from the UK during a week at a special camp in Chicago.

Before they'd even got on the plane, Jess had shouted "bomb" in the airport.

Teenage Tourette's Camp was one of those documentaries you knew you weren't supposed to laugh at, which made it all the more hilarious.

The best bits were the catfights between Preston girl Jen and her nemesis Jess who almost had a fist fight on the camp minibus.

To be fair, not a day went by that Jen didn't collapse in tears. Used to being on the giving end of inappropriate language and swearing, it was a new experience for her to be on the receiving end.

Tourette's sufferers can sometimes set each other off which happened with amusing results when the kids went on a day trip to Chicago.

Like dominos, they fell into a mass of uncontrollable shaking and swearing.

Sam even yelled "twin towers", to the horror of himself and some nearby Americans, The kids all returned better people with more confidence but, let's face it, the documentary was mainly cashing in on the comedy value.
