Wonder if Taylor's body movements are a carry-over from his Easter Bunny days. They seemed oddly appropriate when he was wearing the bunny suit on that episode. 'course, it could be the other way around and his strange movements may have gotten him the bunny gig.
My half sister had Tourette when she was growing up. She took medecine for it, which kept her so doped up that she had a hard time in school. They found by giving her high doses of B vitamins they could reduce her meds by half and that worked great for her.
I doubt that he has Tourette Syndrome. I've looked at him standing in the balcony while others are singing and he is still and watching.
Maybe Taylor has a mild case of scoliosis. That would explain the awkward jutting out of the hip and odd angle of the shoulders.
Anyway, he should be thankful for these quirks...they will keep Paula from trying to jump his bones.
