Teacher was teaching Mahabaratha to 6th std students.
�Kans heard devaki�s 8th son would kill him. So he put devaki & vasudev in prison.
1st child was born.
Kans killed it by poison. 2nd Kans killed by sword. 3rd was born n so on�
At this point a boy raised his hand for a doubt.
Teacher : What?
Boy : �If kans knew that the 8th son would kill him, why did he put devaki & vasudev in SAME jail?�
Teacher fainted !!
