I'm curious now if there are English words (American or the fancy kind) that non-native speakers commonly over-pronounce when goofing around in a similar way.
I can't remember where I saw it but there was a Polish guy who could not say "earlier". He kept saying it like "air lee air" and eventually gave up and said "before" with almost no accent.
Americans basically did this with the English phrase 'each to their own', by saying 'to each their own' just to sound fancier. Then it caught on and now you all say it this way.
