10 Best Brooklyn Nine-Nine Cold Opens

10. I Want It That Way

Even for a detective, it can be incredibly easy to get distracted on the job. That's doubly true if you're Jake Peralta and the jingling of keys is enough to occupy you for the better part of the day. Sometimes, that distraction can happen at a really inappropriate time.

While running a police lineup with a witness, Jake found himself in a unique position. The witness didn't see the person who committed the crime but she did hear him singing "I Want It That Way" by the Backstreet Boys. As such, the only logical thing to do was have five members of the lineup sing the song.

Naturally, Jake got way too caught up in the moment and the quality of the song. The lineup actually delivered a solid rendition of the boy band classic, much to Jake's delight. Unfortunately, Jake forgot that the witness was there to identify her brother's murderer. It was an awkward moment to say the least.
