Johnny was doing his math homework & saying:“2+5, the son of a bitch is 7”
“3+6, the son of a bitch is 9...”
His Mom : What are you doing?
Johnny : I'm doing math homework.
Mom : This is how your teacher taught you?
Johnny : Yes
Infuriated, Mom asked the teacher the next day -
'What are you teaching my son in math?'
Teacher : Right now, we are learning addition.
Mom : Your teaching them to say 2+2, the Son of a bitch is 4?
Teacher after laughing : What I taught them was, 2+2, The Sum of Which is 4
