Always gets the English when they come over first.

This is actually worthy of its own little section, I think.
There's also phrases such as "Sure you're not", "You know yourself" etc...

Also - example: An English teacher is touring Dublin doing lectures on negatives and positives and he says "There are examples in English where a double negative can be negative, and examples where a double negative can be positive but there is no example of a double positive being negative"
From the back of the hall comes the comment - "Yeah, right!"

We use that in Glasgow as well - mind you, there's a large Irish community in Glasgow, so it's not surprising!
