Bobby's In Trouble

Bobby was in kindergarten. "For homework, I want all of you
to go home and find out the first four letters of the alphabet,"
said the teacher. So when Bobby got home, he went to his mother,
who was talking on the phone.
"What's the first letter of the alphabet?" he asked.
"Aw, shut up," said his mom. Next, Bobby went to his brother,
who was watching TV.
"What's the second letter of the alphabet?" Bobby asked.
"FREAKAZOID!" exclaimed his brother, who had not heard a word
of what Bobby had said. Next, Bobby went to his sister, who had
on her headphones and was dancing around like crazy to a song.
"What's the third letter of the alphabet?" he asked.
"Yeah! Yeah! Yeah!" she said. Next, Bobby went to his dad,
who was taking out the garbage.
"What's the fourth letter of the alphabet?" Bobby asked.
"Trash, trash, trash!" his dad said. The next day at school,
Bobby's teacher called on him.
"Bobby, what's the first letter of the alphabet?" she asked.
"Aw, shut up!" said Bobby.
"Who do you think you are?" she asked angrily.
"FREAKAZOID!" answered Bobby.
"Do you want to go to the principal's office?!!"
"Yeah! Yeah! Yeah!" he said. So, his teacher took Bobby to
the principal's office.
"What do you think this school is?" demanded the principal.
"Trash, trash, trash!"
