Super Troopers (2001)

Sometimes it just isn't your day. After years of goofing on the job, five screw up Vermont state troopers suddenly find themselves about to be out of a job due to budget cuts. They have spent their days pulling pranks of one kind or another on each other as long as they can remember and the need to shoot straight hits them all like a ton of bricks. With only one chance left to save their jobs, the troopers must solve a murder faster than their arch rival department from Spurbury. The further they dig into the investigation, the more they realize they might not be equipped to deal with real police work but they are willing to give it a go and pull themselves up by their bootstraps and get down to business.
