Chanler's vocabulary is simply amazing (yes I am biased) and he has mastered some pretty complex words, but there are a couple of words now and again that he just has wired in wrong, and he consistently says the them the same way - eventually they just flip and he starts saying them the way that everyone else says them.

Currently we have elfluent (the pachyderm with the trunk), hosible (where the ambulances go) and murdicle cars (the open air kind). Too funny :)
