A group of six year olds are in a maths class.
"If there are 5 birds on a fence and you shoot one, how many are left?" asks the teacher.
Billy puts his hand up. "None Miss." he answers, "The others would fly away."
"The correct answer is 4 Billy but I like the way you think." laughs the teacher.
"Ok then Miss, I've got a question for you." says Billy.
"There are 3 women eating ice cream cones. One's licking, one's biting and one's sucking. Which woman's married."
"The one sucking?" answers the teacher nervously.
"Actually, it's the one with the wedding ring on." says Billy.
"But I like the way you think."
