Who?

On opening day, the teacher was trying to acquaint herself with her new charges. She asked a boy his name, and he replied, "My name is Juley."

She told him, "Please use your formal name until I learn who you all are better. Next time 'Juley', please say, 'My name is Julius'."

The teacher then turned to the next boy and asked him his name. He responded, "My name is Bilious."
