Nina and Sam try to break the world record for longest onscreen kiss on The Bachelor

The stakes just got higher on The Bachelor...literally.

Sam Wood and Nina climbed to the top of the Sydney Harbour Bridge on last night's episode to try to set a new Guinness World Record for longest onscreen kiss.

As first pashes go, you can't ask for better scenery. We hope they popped a couple of breath mints beforehand.

Did they make it past the record 3 minutes and 48 seconds? Did a fear of heights get the best of them? Watch the video above to find out.

How can the other ladies compete with that? Bachelor villain Sandra couldn't. She got the boot...and of course, Nina got a rose.
