The Joke is on Little Miss Naughty is the 1st episode of the first season of Mr. Men and Little Miss. It was first broadcast on 5 September, 1995.
Mr. Nosey, Mr. Tall, Mr. Dizzy, Little Miss Greedy, Mr. Strong, Little Miss Twins, and Mr. Tickle go for a picnic on the beach. But Little Miss Naughty was also there playing tricks. First she hid a mouse trap grabbed Mr. Nosey's nose, made a hole in Mr. Dizzy's boat, and lastly filled the salt shaker full of sand. But Little Miss Twins, Mr. Tall and Mr. Tickle taught her a lesson. Mr. Tickle put her on a very tall chair and took the ladder off. When they went home they put Little Miss Naughty down. But then she got hungry. So Mr. Strong gave her an egg. When Little Miss Greedy gave her and she shook the salt shaker out came sand.
