Misheard words

We were talking in class one day about orality vs. aurality, and how lots of times children mishear words. I did that a lot. Thought I'd give you some examples.

Bemus = Venus... my parents still call it Bemus whenever I'm around. they think it's cute.
Prentzle = Pretzel
Flinger = Finger

I've never looked at these words in writing before. It's a weird feeling. And I am trying to figure out the significance of why these words were the ones I happened to mispronounce.
