COLLIER COUNTY, Fla. - A band director on trial for having a sexual relationship with a student took the stand in his own defense. Robert Hamberg showed jurors his tongue, trying to prove the teenage girl is lying about their affair. However, his testimony may have done more harm than good.

Hamberg admits he and the teen did meet in a dressing room, but only to go over lessons, or listen to her family problems.

The former band director says he isn't even capable of using his tongue to kiss or have oral sex because of an extra piece of skin. He showed the jury he can't stick his tongue out past his bottom teeth.

When asked by his attorney if there was anything he regrets doing, Hamberg answered by saying "being naive". He said heard of teachers being taken advantage of, but never thought he would be put in that position.

It was because of that statement, having to do with his teaching past, the judge then had to allow the jury to hear about testimony he had previously banned. The State was allowed to ask Hamberg how he met his current wife, Diane. The jury listened to the former teacher say they met when she was 14 and he was her band director. Hamberg said he left the school he was teaching because the situation became uncomfortable. They married when Diane was 18.

The State announced they will be calling a last minute witness Thursday. Hamberg's wife before Diane, whom they say will testify he has no medical issues having to do with his tongue.
