One day little Johnny's teacher was teaching the
class about agriculture. To help with this, she
was showing pictures of farm equipment. She puts
up the first picture, "What is this a picture of
class?" she asks. 

Little Suzy puts up her hand and Johnny sticks up
his hand. Of course, the teacher just knows that
Johnny has something dirty in mind and picks 
Suzy.

"What is this Suzy?". 

"Its a rake". 

"Very good, now can anyone tell me what this is?"
she asks and points at the next picture. Johnny's
hand shoots up and, little Anne politely puts up
her hand, and once again the teacher ignores 
little Johnny. 

"That’s a pitchfork" says little Suzy. 

"Very good, now can anyone tell me what this is?" 
The teacher asks once more. 

Dead silence, only one student has their hand up,
and of course its little Johnny. Seeming as 
though no one else was volunteering, the teacher
asked Johnny. "OK Johnny, what is this?". All of 
a sudden Johnny realizes he doesn't know the 
answer. "UH, UH, its a shovel, yeah, it's a 
shovel." 

"No Johnny, this isn't a shovel, this is a hoe". 

"What?!?! My sister's a hoe and she doesn’t look
nutin' like that!!"
