A little boy was doing his maths 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?
Boy: I'm doing maths homework.
Mom: this is how your teacher taught you?
Boy: Yes.
Infuriated Mom asked the teacher the next day- 'What
are you teaching my son in maths?'
Teacher: Right now, we are learning addition.
Mom: You teaching them to say 2+ 2, the So...n of a bitch
is 4?
Teacher after laughing: What I taught them was, 2+2, the
sum of which is 4
