post senior pranks you've done or heard of. they can just be regular school pranks also...
my class plans to do this one....
we will take 4 chickens
number them 1, 2, 4, and 5
we will then proceed to let them loose inside of the school
they will find them and be like, "WTF! wheres 3!!??" and go on a huge search for #3, when there really is no 3 at all....
last year, the seniors disassaembled my principals car and reassembled it in her office. HA! it was glorious.
