Next time I'm at the bank I am going to try to rob the vault.
Do you think it will be easy to rob the bank?
No, but I bet it would be fun.
Robbing a bank is dangerous and you could get shot for breaking the law. It is better to avoid robbery and just earn money the old fashioned way.
I'm bad and don't want to show that money can't buy happiness.
You will end up in jail if you attempt to rob a bank by yourself, and then you won't be showing anyone anything. You need to seriously reconsider this plan as there are better ways to have fun.
