Want a real snake on a plane story?
My step mother sold her boa to a friend after college. He friend needed to get it back home and rather than go through all the bells, whistles and hoops of carrying a snake on a plane she just put it in her shirt where it wrapped around her bra and settled in. During the fight the snake decided to shift positions and the man sitting next to her saw that her "breast" was moving. She noticed his observation, turned to him and said, straight-faced "I just had them done and the doctor said that they might move of their own accord for a few days." The man nodded and returned to reading his newspaper.
