One day, Little Johnny's class was reviewing the alphabet. His
teacher knew that he had an ''advanced'' vocabulary for his age, so
she was trying to avoid calling on him. When the teacher asked for a
word beginning with "A", Little Johnny raised his hand. The teacher
knew he would say "ass" so she called on Mary Lou, who said ''apple".

This continued through most of the alphabet, because his teacher knew
that there was a cuss word that Johnny would say for every letter of
the alphabet. Then she got to ''R''. She thought for a moment, but
couldn't think of any cuss words that began with R, so she called on
Johnny.

''R is for rats - big FUCKING rats, with twelve-inch cocks!''
