John Landis’ comedy classic may not have invented the toga party, but it certainly set the standard for all onscreen college parties—toga-clad or otherwise—in the nearly 40 years since its release. The studio even mounted a series of toga parties at colleges around the country as a way to promote the movie, and really show American co-eds how it’s done. Live band? Check. A generous enough male-to-female ratio that even the least popular guys have a dance partner? Yep. A semi-synchronized dance routine? Uh-huh. That one weird, seventh-year undergrad who seems oblivious to all that’s happening around him but is clearly having the best time? Animal House has got that, too.
