When my brother was very young, he would pronounce "hamburger" as "hangerber". This became a standard alternate pronunciation in our family. At about 8 years old, while having dinner at a friend's house, I called them "hangerbers" and everyone laughed. I was surprised at their ignorance, and spent a good long time convincing them that "you can say it either way".
