Cylinders, That's Right, Cylinders

So the kids had a project at school the other day where they made cylinders, and then drew cylinders all over the outside and then the teachers stuffed them with candy.  My sons is pictured above.  I did not know the details of the project when he first brought his work home.  In fact, I didn't even notice it until it later in the evening as I was cleaning off the counter.  As I moved it, something caught my eye.  I quickly pointed the project out to my husband and we both were shocked.  I asked my son what exactly it was that he had drawn all over the paper.  He seemed  a little irritated by the questioning, which made me more suspicious.  He said he didn't want to say what it was.  My husband asked if they were rockets.  My son said no.  I asked if they were dumbbells.. Again he answered no.  We questioned him a little more, and demanded he tell us what he had drawn.  He still did not want to say.  Finally I asked him if it was his pee pee he had drawn all over the paper.  I stressed that this was inappropriate and that he would get into trouble at school if he was to continue drawing this type of stuff on his assignments.  At this point, he got a little mad.  That is when he finally admitted that what he had drawn was cylinders.  That's right, cylinders.
