So Billy raised his hand politely to ask if he could be excused. Of course the teacher said yes, but asked Billy to be quick.
Five minutes later Billy returned, looking more desperate and embarrassed. "I can't find it", he admitted.
The teacher sat Billy down and drew him a little diagram to where he should go and asked him if he will be able to find it now. Billy looked at the diagram, said "yes" and goes on his way.
Well five minutes later he returned to the class room and says to the teacher "I can't find it".
Frustrated, the teacher asked Tommy, a boy who has been at the school for awhile, to help him find the bathroom.
So Tommy and Billy go together and five minutes later they both return and sit down at their seats. The teacher asks Tommy "Well, did you find it?" Tommy is quick with his reply: "Oh sure, he just had his boxer shorts on backwards"
