Canada's office was located less than a mile from Charlotte/Douglas International Airport. Production was constantly stopped to allow planes to pass. Sometime pausing as many as 6 times in the middle of takes.
Paul's line "You're management material", as well as Canada's reaction, were ad libbed.
Sections of the movie were sped up slightly to make Ruby appear more annoying.
The line "I've got to take my mom to get an abortion" was ad libbed. The script had an entirely different joke.
The background extras in the pool scene were almost entirely comprised of the film's crew. In fact, the only person in the crew not to appear in the cast or as an extra at some point was the Director of Photography, Ben Jack.
