3rd grade teacher

The third grade teacher asks the students what their dads do for a living

little Susie says, “My dad’s a dentist, he fixes people’s teeth”

Mark says, “My dad’s a carpenter, he builds houses”

The teacher asks little Johnny, “What does your dad do”

Johnny replies, “My dad doesn’t do nothin’, He’s dead”

“Oh my gosh” stammers the teacher, " I didn’t mean to be insensitive. What did he do before he died"?

“Well he turned blue and pooped on the carpet”
