Everything you need to know about "Let's Be Cops" is in the title. Two guys (the hilarious Damon Wayans Jr. and Jake Johnson) dress as up as police officers for a costume party and find themselves -- "Desperately Seeking Susan"-style -- confused for the real thing. And it turns out that imitating the real thing is a really good time. Why would it backfire?

In this slightly-NSFW clip, watch as the guys befuddle their neighbors by rolling out in a squad car. 

"Let's Be Cops" arrives in theaters August 13.
