Little Johnny Thinking Brick
The first kid said, "I think about my dad. He is a construction worker".
Another said, "I think about our new house".
Then the teacher thought, "Why don't I ask Johnny? After all, what can he say about a brick that would be improper?" So she asked, "Johnny, what do you think about when you see this brick"?
Johnny said, "Naked chicks"!
The teacher was horrified, "But why, Johnny? Why? This is a brick"!
Johnny said, "But that's what I always think about"!
