Teacher asks her class of 7 year-olds a maths question "If there are ten crows sitting on a wall and you shoot one with your air rifle, how many are left?"
Tommy throws his hand up "None, Miss!"
"No Tommy", she says, shaking her head. "If you shoot one then nine will be left."
"No, Miss," Tommy replies, "If you shoot one the rest will fly away in fright."
The teacher cocks her head and says "Well Tommy, that's quite an interesting thought."
"Yes Miss", Tommy pipes back up. "It's called lateral thinking, or thinking outside the box. Me Dad's been teaching it to me through the internet."
"Well, how interesting Tommy. Can you give the class an example?"
"Sure Miss. Three women sitting in a park eating ice cream cones. One's holding her cone in a tissue, very fussily, and licking at it with extreme care. The second is swapping her cone from hand to hand to avoid any drips going on her and taking careful licks so as not to smear her lipstick. The third is holding her cone in a real tight double-handed grip round the base, shoving her tongue right into the middle of the ice cream, then pushing the entire ice into her mouth and sucking greedily. Which one of the women is married?"
The teacher paused, reflects, then replies "Well, I suppose it would be the third one, who is hamdling her ice cream cone with so much expertise."
"Er no, Miss. Actually it's the one wearing the wedding ring, but I like the way you're thinking!"
