Two friends are seating in a restaurant and speaking. The first asks,

“What are your sons’ professions?”

The other replies, “The first one is an engineer, the second one is a doctor. The third one is a business man and my last son is a thief!”

“What?” responds the first one with amazement, “Why don’t you kick him out of the house?”

“Man, how can I? He is the only one who earns money!”
