It isn't the least bit surprising to say that my fascination with Blueberry Inflation and Body Inflation in general stems from watching Willy Wonka and the Chocolate Factory as a small child, but what I find interesting at the moment is, originally as a little kid (after first watching the scene) the notion of someone inflating big and round like a balloon actually scared the crap out of me. Even as a small child I knew it was all made up, but I was irrationally afraid of blowing up like a balloon. I also had an aversion to blueberry pie (and pie in general) after seeing the movie, although I never told anyone ever; I just avoided it.
I'm curious if anyone else's fascination with inflation started out as an irrational fear or something similar. I've tried on occasion to see if there was any kind of phobia that would be even marginally related to this, but most responses you get to internet searches involve a fear of balloons in general or fear of inflation as it relates to economics.
On a side note, as a little kid, I had a vague fear of the dark that turned into a love of horror films as I got older, so I guess there might be some psychological correlation between fear and fascination.
I was never scared of it per se, but there was one calvin and hobbes comic where calvin imagines himself inflating at the dinner table because he was forced to eat one bit too many. It was highly unsellting... not sure why.
