I don't really know..it definitely isn't singing tho..that's for sure. Oh! but my arms are double jointed.^^ I can make them look all weird and broken. It used to creep out some of my friends, so naturally I would always do it around them. cool
I can vibrate my legs, hands, arms, fingers. I'm double jointed in the middle joints of my fingers. I can stretch until I black out. I have a "meaty" mouth that allows me to do far more facial expressions than most people. I can wrap my genitalia around my ankle while standing up.
I can dance when I want to. smile
