Boobs bouncing in slow motion. Can you think of a better way to test the new iPhone's slow-motion camera feature? Didn't think so.

The new iPhone 5s has only been out a few days, and slow-motion videos are popping up on YouTube everywhere - which is going to get really annoying, really fast.

One guy used it to record himself destroying two old iPhones by pouring water on them, slathering them with peanut butter and having a dog lick it off, and lighting one of them on fire, but that video is pretty boring so we're not going to post it.

The best slow motion iPhone video we have seen so far is the one above from some guy who convinced his girlfriend to jump up and down while he filmed her boobs.

You sir, are the winner of the Internet....for now.
