Bad Example

A teacher says, “Okay, class. Today we're going to be talking about the tenses. If I say, I'm beautiful, which tense is it?”
Little Johnny raises his hand and says, “Obviously past tense, Miss.”

Grandpa and Little Johnny

Grandpa and Little Johnny are sitting on a bench in the park. Johnny asked, "Grandpa are you going to take that new Viagra?"
Grandpa looks at him and says "No Johnny, I will not."
"But Grandpa, why?" asks little Johnny.
Grandpa replies. "Because there is no sense in putting lead in your pencil if you have no one worth writing to."

Little Johnny - Poker

Little Johnny had become a real nuisance while his father tried to concentrate on his Saturday afternoon poker game with friends and relatives. His father tried every way possible to get Johnny to occupy himself: television, ice cream, homework, video games... But the youngster insisted on running back and forth behind the players and calling out the cards they held. The other players became so annoyed that they threatened to quit the game and all go home. At this point, the boy's uncle stood up, took Johnny by the hand, and led him out of the room. The uncle soon returned back to the poker table without Johnny, and without comment the game resumed. For the rest of the afternoon, little Johnny was nowhere to be seen and the card players continued without any further interruptions.
After the poker game ended, the father asked Johnny's uncle, "What in the world did you say to Johnny? I haven't heard a peep from him all day!"
"Not much," the boy's uncle replied. "I just showed him how to masturbate."
