CHARTERED ACCOUNTANT vs. MBA- An old but funny difference..

7 Chartered accountant and 7 MBA are going from Pune to Mumbai. So they both gether at pune station....Scene-1(pune-mumbai)- 7 CA's take only one tickets and 7 Mba buy all 7 ticket.... MBA r deseperately waiting for TC to come..... When TC comes, All 7 CA get in one toilet, so when TC knocks,one hand come out with tickets and TC goes away.....Now on return journy all of them dont get a direct train to pune. So they all decide to take a passanger till lonavala, from there they can easily get a LOCAL to pune.
