Funny Jokes

My father began teaching business classes at the local prison through a community college. On his first night of class, he started a chapter on banking. During the course of his lecture, the subject of ATMs came up and he mentioned that, on average, most machines contain only about $1,500 at a given time.
Just then, a man in the back raised his hand.
"I'm not trying to be disrespectful," he told my father, "but the machine I robbed had about $3,000 in it."
