For some reason I can see him skewering marshmallow Peeps, setting them ablaze and then squishing them between two blocks of Honeyduke's secretly in his chambers at the end of the day after capturing countless dunderheads snogging in the nooks and crannies of the castle.
On Feb. 15, the points would only show negative numbers for three houses until Dumkbledore noticed. [only Gryffindor would get any points restored.]
ENJOY IF YOU CELEBRATE THIS HOLLIDAY
BE SNARKY IF YOU DON'T
