One day a father and son had a short conversation.
Son: Dad, I have a drug test tommorow. What should I do?(while laughing)
The son is a drug user but his father didn't know about it.
Father: Ha! Then why are you laughing at. Take your review!
Whose the drug addict now?
Laughter is the best medicine! So, LAUGH NOW STEEMIANS!
Respect!
