10. ''A Tale of Two Parties'' season 1, episode 20
Omega Chi hosted a huge Greek party, deliberately excluding Kappa Tau. When the KTs' attempt at a rival party fails, they resort to sneaking and stealing liquor from their mortal enemies. Dressed in Omega Chi argyle, khaki, and popped collars, it's one of the few times that these slackers enter the future stockbrokers of America's house, prompting Cappie to utter possibly the best reference to another TV drama equally fond of fiestas, ''It's like we've died and gone to Gossip Girl!''

9. ''Camp Buy Me Love'' season 3, episode 18
Even though most of the CRU kids weren't old enough to enjoy the 1980s, it doesn't mean they don't think it's a good party theme! Dobbler's was the site of 80s night, where Greeks and non-Greeks flocked to pay tribute to John Hughes and dress up as their favorite version of Madonna. Ashleigh prepared for the event for an entire week by testing out fashions and studying the best films of the decade, later applying their lessons to Rusty's real romantic troubles.

8. ''Formally Yours'' season 2, episode 7
Socially awkward Max pulled out all the stops for his new girlfriend Casey, by accompanying her to the Zeta Beta Zeta spring formal in a horse-drawn carriage. Kappa Tau had planned a prom, which excited Rusty, who (of course) had missed his own in high school. When that backfired, Ashleigh brought little Cartwright to the ZBZ formal as her date and the two shared a kiss on the dance floor. Awww.

7. ''Let's Make a Deal'' season 2, episode 3
Everyone gambled at Omega Chi's Casino Night. Ashleigh's looming credit card debt led her to count cards with Casey, Rusty, and Max, in attempts to win back what she's spent, while Cappie and Rebecca put their relationship on the line. Everything is flashier in Vegas, so of course there was plenty of sequin-clad sorority girls and sharply dressed men, making even Cyprus seem like Sin City.

6. ''See You Next Time, Sisters'' Season 2, episode 6
The annual Honors Engineering Galileo party moved to the Kappa Tau house, bringing together Engineering students with their Greeks peers. Recipe for disaster? Yes? but not how you'd think. After discovering the engineers' drink of choice, a potent Aerosol death juice guaranteed to ''maximize efficient inebriation,'' Cappie turns into a protective mother hen, kicking out the rowdy engi-nerds from his respectable establishment.

5. ''The Big Easy Does It'' season 3, episode 17
To celebrate Fat Tuesday, Kappa Tau hosted its annual Mardi Gras party, where brothers are instructed to only bring girls they know they'll get lucky with. Best part? Beaver leading multiple parades throughout the night and pledges baking lifesize babies into the house's King Cakes.

4. ''I Know What You Did Last Semester'' season 3, episode 11
The Fairytale Ball made everyone a bit more romantic. The fabulous costumes — Rapunzel and her foot-long blonde wig — and grand gestures — Calvin and Grant stepping out onto the dance floor as a couple — created a storybook ending that was indeed happily ever after.

3. ''At World's End'' season 2, episode 22
On the brink of a two-week social probation, Kappa Tau decided to celebrate their last weekend of freedom by throwing an ''End of the World'' party. Revelers got into the spirit of Armageddon by wearing disaster gear, like smoke masks, while apocalyptic films were projected on a big screen. This theme carried a hefty significance as many quickly realized what — and who — they truly want.

2. 'The Great Cappie'' season 1, episode 12
While the Greeks were under new totalitarian-like social restrictions from Dean Bowman, Casey and Ashleigh pushed for a secret ''prohibition'' style party with Kappa Tau. Getting the girls to don flapper dresses and garter belts was easy compared to the effort it took to get them to party with the KTs, but in the end, the costumes, music, and decorations all transported these CRU Greeks to the roaring '20s. Equipped with enough ''liquor to incapacitate David Hasslehoff,'' the KTs distracted an unexpected guest, while Ashleigh played lounge singer to the basement speakeasy crowd.

1. ''Liquid Courage'' season 1, episode 5
The most memorable party at Cyprus Rhodes came during one of the very first episodes. For Homecoming, new Kappa Tau pledge Rusty hoped to prove himself by working on the legendary Mt. Vesuvius, a beer-spewing volcano. When the party's main attraction malfunctions, it was up to the unlikely Spitter to save the day (he may be a late bloomer, but he ''is'' a polymer science major). The result is a success, and party, of epic proportions.
