Little Johnny: "None."

Teacher: "Listen carefully: Four crows are on the fence. The farmer shoots one. How many are left?"

Little Johnny: "None."

Teacher: "Can you explain that answer?"

Little Johnny: "One is shot, the others fly away. There are none left."

Teacher: "Well, that isn't the correct answer, but I like the way you think"

Little Johnny: "Teacher, can I ask a question?"

Teacher: "Sure."

Little Johnny: "There are three women at the ice cream parlor. One is licking, one is biting and one is sucking her ice cream cone. Which one is married?"

Teacher: "The one sucking the cone."
