I have a couple. I work with a guy for whom English is a second language. His one funny is saying "Today morning", rather than 'this morning'. It is probably not incorrect - it just sounds funny to me.
The other is the use of "off of" - this seems an American usage (e.g. "he jumped off of the box"). I really can't see what the "of" is in there for ("he jumped off the box"). Just seems like a wasted word to me...
edit: off topic - I just saw how similar Grancey's cat and my cat look.
