Sure. There was a girl named Gretel. Gretel tried to say 'I scream, you scream, we all scream for ice - cream' as fast as she could. But instead, it came out like 'I sceam, you sceam, we all sceam for ice - cweam'. Her little brother laughed so hard that milk came out of his nose.
There was a wizard named Wiz. Wiz liked to practice tongue twisters in his free time. One of his favorites was 'Unique New York, unique New York, you know you need unique New York'. One day, while he was casting a spell, he accidentally started saying the tongue twister instead of the incantation. His spell went all wrong and instead of creating a beautiful flower, he created a bunch of talking tongues that kept repeating the tongue twister. It was quite a chaos in his wizard tower until he finally managed to reverse the spell.
A fox named Felix once tried to say 'Fuzzy Wuzzy was a bear. Fuzzy Wuzzy had no hair. Fuzzy Wuzzy wasn't fuzzy, was he?'. But Felix the fox had a lisp, so it came out as 'Fuzzy Wuzzy wath a bear. Fuzzy Wuzzy had no hair. Fuzzy Wuzzy wathn't fuzzy, wath he?'. All the other animals in the forest found it so hilarious that they made Felix repeat it over and over again for their entertainment.
