One day, Little Johnny's teacher asked the class, "Children, if you know
the answer, please raise your hand! Tell me things you can suck!"
"Ice cream, ma'am!" Little Mary answered.
"Good, Jane." teacher said, "Anyone else?"
"How about a lollipop?" said Steven.
"Very good, now it's your turn Johnny!" the teacher said.
Little Johnny, sitting at back then answered, "A lamp!"
The teacher and all of the students wondered about Little Johnny's answer.
Then the teacher asked him, "Johnny, why do you think one can suck a lamp?"
"Well, last night when I passed my parents' bedroom", Little Johnny
answered, "I heard my mom say, turn off the lamp, honey and let me suck
it."
