It is no secret that things are said a little bit differently in different parts of the world, even if the places speak the same language. However, it is one thing to acknowledge that and appreciate the differences, and it is a whole other thing to make fun of how other people say something. If someone from the UK says queue instead of a line, it is not something to make fun of, just a difference!
It can be funny to see how things are said between different people around the world, and even funnier that someone might not even understand them, even if it's the same language.
