Bobby and His Family's Responses

So, there was a kid named Bobby, and he was writing notes. He asked his mother, who was on a phone call, "what is one plus one?" She said, "I HATE YOU." Then he asked his brother what is 2 + 2, who was watching a Batman movie, said, "NU NU NU NU NU NU NU NU NU NU BATMAN!" Then he asked his dad what is 4 plus 4, who was playing football, said, "85 SMACK EM DOWN!" Then he asked his sister 8+8, (she was playing with barbies), and she said, "My buns are burning." Then he went to school and told her teacher the first note he wrote down. The teacher sent him to the principal’s office. The principal yelled, "WHO DO YOU THINK YOU ARE?!" Bobby said, "NU NU NU NU NU NU NU NU NU NU BATMAN!" The principal yelled, "HOW MANY SPANKINGS DO YOU WANT?!" Then he said, "85 SMACK EM DOWN!" Then he walked away from the principal’s office and said, "my buns are burning."
