Not a Japanese student question, but still a language question.  Occasionally when I am listening to a Japanese person introduce himself through an interpreter, when the person finishes the introduction the interpreter says something ridiculous like "Let's have fun together."  If it had only happened once I would assume the person was just strange, but since the same thing has happened several times I'm wondering if it's a "thing."  Does anyone have an idea what they might actually be saying?
