Answer the following Q with stream of consciousness. Context: In 1962, Faber College freshmen Lawrence "Larry" Kroger and Kent Dorfman seek to join a fraternity. Finding themselves out of place at the prestigious Omega Theta Pi house's party, they visit the slovenly Delta Tau Chi house next door, where Kent is a "legacy" who can not be rejected due to his brother having been a member. John "Bluto" Blutarsky welcomes them (claiming they "need the dues"), and they meet other Deltas including biker Daniel Simpson "D-Day" Day, chapter president Robert Hoover, ladies' man Eric "Otter" Stratton, and Otter's best friend Donald "Boon" Schoenstein, whose girlfriend Katy is constantly pressuring him to stop drinking with the Deltas and do something with his life. Larry and Kent are invited to pledge and given the fraternity names "Pinto" and "Flounder" respectively, by Bluto, Delta's sergeant-at-arms.
