A teacher asked this little kindergarten girl
"What is the first letter of the alphabet?" She didn't know the answer. Her teacher told her that her homework is to find out what the first letter of the alphabet is. So she goes home and she asked her big sister who was doing her own homework,
"What is the first letter of the alphabet?" The little girl asked.
"SHUT UP!" Her sister yelled.
"Okay!" the girl said to herself. Then she goes and asks her mom who was talking on the phone,
"What is the first letter of the alphabet?"
" Yeah, okay" Her mom answered.
"Okay the girl said to herself. The she goes and asks her dad who was watching the foot ball game on TV,
" YES! Touch down 49!" her dad answered.
" Okay" the girl said to herself" then she goes to her grandpa who was cooking buns,
" What is the first letter of the alphabet?" she asked her grandpa. All of a sudden the smoke alarm goes off!
"MY BUNS ARE BURNING! MY BUNS ARE BURNING!" Grandpa screams.
"Okay" the little girl says to herself. The next day her teacher asked her,
" What is the first letter of the alphabet?"
"SHUT UP!" The girl screams.
"Do you want to go to the principals office?" her teacher asked her.
"Yeah, okay" She answers. So when she got to the principals office he asked her,
"How many spankings do you want?"
" YES! touch down 49!" she said. SO she gets 49 spankings and then she says,
"MY BUNS ARE BURNING! MY BUNS ARE BURNING!"
