The following one took a long time to sink in and I still "think" I understand it :)
Once, a teacher in a school asked a disobedient student "to stand up on the bench and hold ears with hands".
The Student gave very irritating reply to the teacher," If I stand up, I won't have to hold my ears" & "If I hold my ears, I have to sit down".
The teacher was furious and started shouting at the student...
But the whole class and even the teacher started laughing after the investigation was over...
Reason: The Student was wearing the same pant that his dad used to wear. So, there is only one pant for both the son and the father.
So, the student intelligently replied as " If I stand up, I won't have to hold my ears" & "If I hold my ears, I have to sit down".
