ok once there was three brothers, the first one is called gangster, second called knife, third called trouble.
One day, trouble went missing.
So, Gangster took knife with him to the police station to make a police report.
The policeman asked for their names.
Gangster said "My NAME is GANGSTER!"
The policeman then asked what was he doing here.
HE said "I came here WITH KNIFE to look for TROUBLE!"
