Little Johnny was eating breakfast one morning and got to wondering about things: "Mommy, why has Daddy got so few hairs on his head?" he asked his mother.
"He thinks a lot," replied his mother, pleased with herself for coming up with a good answer to her husband's baldness.
"So why do YOU have so much hair?" Little Johnny asks.
"Go eat your breakfast!" snarled his mother.
Teacher: Railroad crossing at the track. How many R's in that?
Little Johnny: There are no R's in 'that'.
After his mother yelled at little Johnny, he retaliated, "Don't shout at me! I am not dad!"
Teacher: Johnny what time is bedtime at your house?
Johnny: 8:30 PM, ma’am.
A few moments later
Johnny’s Best Friend: So what time did you go to sleep last night?
Johnny: 1:00 AM, after watching two movies and getting a snack.
