The last first day of high school, the last birthday at home (trust me, this one is the real killer), or the last varsity game.
First day of school sign for new students/ take one at the last day and send home
these are the best pranks I have ever seen.
Use for church chorister games - holes are worth certain points, can color them primary/secondary/tertiary and make a point value.Easy to make, lots of fun.
