Student: "Sir, how many holes are there in the net?"

Patient: "Doctor, can you tell me what are your fees?"

Doctor: "For the 1st visit I charge $2000 and the 2nd visit is free."

[The patient then decided to lie.]

Patient: "Doctor, this is my second visit."

Doctor: "In that case, please continue taking the medicines that I had prescribed on your first visit."

Teacher: "Class, we'll have only half a day of school today morning."

Students: "Yaaayyy!"
