Stupid kid in class jokes

One kid in our class was so stupid he had his address tattooed on his forehead.
That way, when he got lost he could mail himself home.
 
Another kid was so stupid he had "left" and "right" tattooed on his toes so he would know which feet his shoes should go on.
Now all he has to do is learn how to read.
 
I knew a person who was so stupid,
the only way he got out of the third grade was to marry the teacher.
 
One kid in our class was really stupid.
He was late for school every day because he kept trying to put his pants on over his head.
