One day, there was this small boy who was uneducated. His parents were fighting and this is what they said.
"
You're a bitch!"
said the father to his wife.
"
You're a bustard!"
sard the mother to her husband.
"
Mom Dad, what's bicth and bustard?"
asked the small boy.
"
Bitch is female and bustard is male"
answered the father.
He then went down the stairs to the ground hall. His sister fell from the chair and said "
fucker!"
. Again the small boy asked his sister "
Sis, what's fucker?"
. "
The chair"
answered his sister.
He then went to the kitchen and saw his aunty cooking chicken soup. As she was cooking, she accidentally drop the chicken. She said "
Shit!"
. Again the small boy asked his aunty "
Aunt, what's Shit?"
. "
The chicken!"
answered his aunty.
The next day, two couples(the small boy's father friends) came knocking on the door. One was a male and the other was a female.
This was the small boy welcome speech::
