Answer:
I can swim but never get wet. I can run but never get tired. I follow you everywhere but never say a word.
I can be hairy and itchy all over. I hang on a stick. I can be the scariest thing you have ever seen. I stand in the middle of nowhere.
My first is high my second damp my whole a tie a writer's cramp.
You may enter, but you may not come in. I have space, but no room, I have keys, but open no lock. What am I?
You throw away my outside you cook my inside. Then you eat my outside and you throw away my inside.
What is yours but only used by others?
