Answer:
I am cracked by Indiana Jones.
I am the only thing that always tells the truth. I show off everything that I see. I come in all shapes and sizes. What am I?
I go inside boots and outside shoes.
I can be repeated but rarely in the same way. I can't be changed but can be rewritten. I can be passed down but should not be forgotten.
I am used when you jump off a bridge for fun.
Runs over fields and woods all day. Under the bed at night sits not alone, With long tongue hanging out, Resting at your feet until we go for a walk
