The line "Sounds like someone got a case of the Mondays" is from which film?

The above line is spoken in the 1999 film "Office Space". In a scene with a key character, Peter Gibbons (Ron Livingston), a female temp worker comes up behind him and says, "Uh oh. It looks like somebody's got a case of the Mondays" (in a childish and rude tone). In another scene when Peter is talking about how he can't be in the office when it gets him too upset, he says to Lawrence (Diedrich Bader), "Let me ask you something. When you come in on Monday, and you're not feelin' real well, does anyone ever say to you, 'Sounds like someone has a case of the Mondays'?" Lawrence answers: "No. No, man. Shit, no, man. I believe you'd get your ass kicked sayin' something like that, man."

The phrase is used here to describe a person who comes to work on Mondays in a bad mood. Also, the phrase is used if someone wants to get their ass kicked by their co-workers. The case of the Mondays if seen as humorous can be a fictitious disorder associated with tiredness, irritability or detachment that comes from going to work after the weekend.

In the Mike Judge film, office drone Peter hates his soul-killing job at software company Initech. While undergoing hypnotherapy, Peter is left in a blissful state when his therapist dies. He refuses to work overtime, plays games at his desk and unintentionally charms 2 consultants into putting him on the management fast-track. When Peter's friends learn they're about to be downsized, they hatch a revenge plot against the company. Is it enough?
