When I was 6 or 7, there were these videos I used to rent called THE MAGIC SCHOOL BUS. It was about a school bus that could shrink and do other things so the students could go on whimsical field trips. There was on episode where the bus got trapped on this one kid's food and was digested. The bus went through all the major organs and eventually got sneezed out. The idea of being digested by a classmate scared the crap out of me, and several other segments of the episode were freaky, such as the bus almost getting destroyed by the stomach acid. I found the whole episode on youtube and it isn't as scary as I remembered it being. I have posted the links below for anyone who wants to waste 20 minutes watching a bad children's show.
