"Math Class" joke
Miss Jones asked young Tommy, "If three birds were sitting on a fence, and the farmer shot one of them, how many would be left?"
"Well," said Tommy, "none would be left because the sound of the gun would scare the others away."
"That's not quite the answer I was looking for, since we're doing subtraction today, but I like the way you're thinking," the teacher said.
The next day, Tommy told Miss Jones that he had a question for her. "If three women were walking down the road, one licking an ice cream cone, one sucking an ice cream cone and one biting an ice cream cone, which of the three would be the married woman?"
"I think it would be the one sucking the ice cream cone," Miss Jones replied.
"Sorry, Miss Jones," Tommy said. "It would be the one with the wedding ring on her finger, but I like the way you're thinking."
