We are going to have alot of fun this weekend!  After we get out of school Thursday we are all heading over to Marc's house for an intense match of backyard professional wrestling.  The reason being that we all like to jump off buildings onto our friends.  Then, toilet papering.  That is a blast!  Like paper snow falling in long, thin sheets, we will terrorize our enemies and their houses.  You can bet there will be more than one unsuspecting parent that will awaken to a yard full of headache.
