A teacher asks her class if anyone can use the word fascinate in a
sentence. Brian raises his hand and says, "The sky is fascinating."
The teacher says, "No that's fascinating."
Jennifer raises her hand and says, "When I saw the tigers at the zoo I
was fascinated."
The teacher says, "No that's fascinated."
So finally Little Johnny raises his hand and says, "My mom bought a
new blouse with 12 pearl buttons, but her chest's so big she could
only fasten eight!"
