Stuttering!!!
 

>>> A teacher is explaining biology to her 4th grade
******** students. "Human beings are the only animals that
******** stutter", she says.
********
******** A little girl raises her hand. "I had a kitty-cat
******** who stuttered", she volunteered. The teacher,
******** knowing how precious some of these stories could
******** become, asked the girl to describe the incident.
********
******** "Well", she began, "I was in the back yard with my
******** kitty and the rottweiler who lives next door got a
******** running start and before we knew it, he jumped over
******** the fence into our yard! "That must've been
******** scary", said the teacher.
********
******** "It sure was", said the little girl. "My kitty went
******** 'Fffff, Fffff, Fffff'... and before he could say
******** "F**ck," the rottweiler ate him!"
