Guinness World Records says that the worlds hardest tongue twister is "The Sixth Sick Sheik's Sixth Sheep's Sick." Try saying that three times fast. Tongue twisters are words that are very similar to each other that are difficult to pronounce, especially when you add a little speed into the mix.
Another popular tongue twister is "Pad Kid Poured Curd Pulled Cold," or "My Sister's Shop Sells Shoes For Sheep." Two of them that we have all heard before are "She Sells Sea Shells By The Sea Shore," and "If Peter Piper Picked A Peck of Pickled Peppers, Where's The Peck of Pickled Peppers Peter Piper Picked? Kids love tongue twisters and always have a good time with them. How many of these can you say?
