Creeping under the staff table at the opening feast, Peeves was grateful that the tablecloth draped to cover the whole side of the table. Professor's feet and most importantly – he – couldn't be seen. Working from one end to the other end of the table, he untied each professor's shoelaces and tied one lace to shoe next to it.

Oh those professors would kill him if they knew . . . But gosh this was going to be amusing when one rose from their seat. This was the punishment for teaching a poltergeist how to untie and tie shoelaces.
