One day, Little Johnny's teacher, Miss Figpot asked the class if they could name some things you can suck!"
"Ice cream, ma'am!" Little Mary answered.
"Good, Jane." Miss Figpot 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 his answer. The teacher asked him, "Johnny, why do you think one can suck a lamp?"
"Last night when I passed my parents room", Little Johnny answered, "I heard my mom say, turn off the lamp, honey and let me suck it."
