Another one I find simply adorable is the placement of a "w" instead of an "r".
But not in a circumstance where its applied in the first syllable (eg: "wabbit"), but rather further in the word.
For example instead of "store" it is pronounced "staw". Especially when it is used in a sentence heavy in that format, along with having less clarity in the "s" sound, sometimes due to excess saliva.

And don't even get me started on when they whisper it.....ohhhh my... :D
