A first – grade teacher was starting a new lesson on multisyllabic words. She thought it would be a good idea to ask a few of the children for examples of words with more than two syllables.
One pupil stood up and said, 
“Mas-tur-ba-tion.” 
Shocked and trying to retain her composure, the teacher said,
“Wow. Four syllables. That certainly is a mouthful.”
“No ma’am,” he replied. “you’re thinking of blow job, and that’s only two syllables.”
