Animal House - ROLE 1: Dean Wormer (John Vernon) ROLE 2: Greg Marmalard (James Daughton). Plagued by Delta House's chronic bad behavior, Faber College's Dean Wormer plots the fraternity's demise with the clean-cut head of rival frat Omega Theta Pi. They're already on probation, notes Greg. But Wormer will not be cowed and puts the Deltas on double secret probation.
