After being spooked by the boys one night, the girls work on their own method of revenge. Mike calls for an end to the pranks but the kids team up to scare Alice. Panicked, Alice smashes the bust of Mike that Carol made for an art contest, which was the subplot, thinking it is the head of a burglar.
