Mary Under had been teaching for a long time. She taught 5th grade for 25 years all while enjoying a plain lifestyle. Having never married, she was not a complicated woman. She always brought the same leftovers in the same Tupperware for lunch. She had one fork, one spoon, one knife, and one bowl. Her classroom had little decoration, and her house was the same way. Since she taught in a small town, everybody knew her, and some current students were children of her former students. One day in class when she was asking her students what they wanted to be when they grew up, a little boy said he wanted to be a comedian, and that he was learning how to do so from his father. ""You know, your father used to be the class clown. He was always putting tacks on my chair and forcing me to get up from my seat."" said Mary. The boy assuredly responded: ""Oh I know all about that, Miss Under. He said he was a rotten child. He made me promise not to pull the pranks he did when he was a kid."" ""Glad to hear that"", Mary said as she got up from her desk chair. Much to her surprise, the boy started laughing. Confused, she sat back down and the boy ceased laughing and looked at her in anticipation. When she stood again, the boy fell out of his desk and was rolling on the floor clutching his stomach from laughing so hard. Angrily, she stormed over to the boy, still giggling on the floor. ""I thought you said you weren't going to be trouble like your father! Did you put a tack on my seat? Answer me!"" The boy got beck in his desk and wiped a tear from his eye. ""No!"" He said with a chuckle. ""My dad told me that the best punchlines in jokes are always Simple Miss Under standing!""
