A teacher was teaching a class of young children and during their English lesson she said to the class, "Right, today we're going to look at words that contain two or more syllables, and I want you to give me an example of a word made up of two or more syllables."  After briefly explaining to the class what a syllable was, she asked "Can anybody think of a word that contains two or more syllables?"

A number of hands went up, and the teacher pointed to one pupil and said "Helen, can you please tell me what your word is?", to which Helen replied "Mas-tur-bate."

"Wow, that's a bit of a mouthful" said the teacher, somewhat shocked to hear such an answer from a child so young.

"No, Miss" said Helen.  "You must be thinking of a blow job..."
