What jokes have you made because your name was misunderstood by others?

People often call my name by other names, and there is that person's name in the class, so every time the teacher calls the roll, we don't know who he is calling, and I feel that the teacher's accent is really strong. He called our names exactly the same, so we couldn't tell them apart, so every time he called the roll, neither of us knew who was calling and who should stand up.
