farm animals roaming the hallways... like.. animal farm. like they're taking over. and then maybe they would have uniforms/masks impersonating school officials.. like, my principal has a sort of afro.. so i would get an afro wig for a pig and have it roam the hallways.. maybe a bow tie as well.
aww.. my school hates pranks its like the most boring-est school in the world. Last time the seniors did a prank a teacher was involved and the teacher got fired and the seniors got into sooo much trouble. =(
