Teacher: "John, what's the matter? Why are you looking so upset?"
John: "My dad is in police station and my mom is in hospital!"
Teacher: "Oh God! Please go home!"
The principal happened to see John leave. He asks the teacher, "Where's John heading to?"
Teacher: "I permitted him to go home because his dad is in police station and mom is in hospital."
Principal: "His dad is a cop and his mom is a nurse... where else they would be?"
