In the classic movie Animal House, after the entire Delta House frat has been thrown out of school, John Belushi's character Bluto castigates his fratmates for sitting around and feeling sorry for themselves.
Responding to Bluto's exhortations to buck up, Stork, another frat member, informs him "it's over."
"Over? Was it over when the Germans bombed Pearl Harbor?" Bluto replies, starting off an inspirational, although historically inaccurate, speech that leads the frat boys to basically destroy the college town, loot the Food King, and most importantly, get even with the college's dean.
