20. Launch Party (Season 4, Episodes 5-6)

“This is like when the freshmen would throw a party and wouldn’t let any of the seniors go.”
Unlike other episodes, “Launch Party” is full of enough memorable plot lines to successfully fill the hour mark. Michael abducts a pizza delivery guy (seriously) after learning he’s been cut from the Dunder-Mifflin launch party. Dwight attempts to prove his worthiness to Angela by selling more paper than Dunder-Mifflin’s new computer program, and Andy’s wooing of Angela culminates with a conference call performance of ABBA.
