A teacher asks the new student her name. The girl replies, "Happy Butt."
The teacher says, "I don't think that's your name. You need to go to the principal's office and get this straightened out."
The girl goes to the principal's office and he asks, "What's your name?" The little girl says, "Happy Butt."
The principal calls the girl's mother to get the truth. After getting off the phone, he says, "Honey, your name is Gladys, not Happy Butt."
The girl exclaims, "Glad Ass -- Happy Butt -- what's the difference?"
