Moondays 

Something people occasionally get a case of on the first day of the modern work week. Add extra "oooo's" as necessary.

Office Worker #1: Good morning.
Office Worker #2: (No response)
Office Worker #3: Sounds like somebody has a case of the Moondays.

The Mondays 

A day generally created for the purpose of making people wish they were someone else. The day you realize you have 4 days of work ahead of you and that they won't be going by fast at all. Symptoms generally include feeling like crap, wishing you were dead, or not showing up for work in general.

Sounds like someone has a case of the Mondays 

Something said by obnoxiously cheerfull bastards when someone is feeling tired and/or cranky. Mondays tend to be a horrible day since it's the first day of the working week. Made famous by the movie Office Space.

Peter Gibbons: 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: No. No, man. Shit, no, man. I believe you'd get your ass kicked sayin' something like that, man.

Case of the Mondays

A phrase used to describe someone that has a bad mood when he or she comes to work or school on Mondays.

OR

A phrase that someone uses if he or she wants to get their ass kicked by their fellow co-workers or school mates.

Jerk #1 - When you come to work on a Monday, has anyone ever told you, "Looks like someone's got the case of the Mondays."?

Jerk #2 - No... No man... Shit, no man... I believe you get your ass kicked for saying something like that.

happy mondays 

Bunch of scallies who made a few million quid then pissed it up the wall. Revolutionised indie, rock and dance music in the process. Also introduced ecstasy to the north of England.

"That DJ was a cunt"
"I know, he didn't even have any Happy Mondays"
