When Emily Burth signed up to model wedding dresses at the Houston Bridal Extravaganza on July 21, she didn't know she'd be purchasing one for herself so soon.

My Fox Houston reports that Burth was wearing a dress down the runway when her boyfriend Trevor Case jumped on stage and dropped to one knee.

The YouTube video of the proposal shows a surprised Burth on the runway while Train's "Marry Me" plays in the background. Case walks the length of the runway and Burth accepts his proposal.

Case says his friends aren't quite as happy with the proposal as Burth is. He told My Fox Houston that his buddies feel they'll have to up the ante when it comes time for them to pop the question.

It seems like men across the globe have been trying to one-up the last guy to propose with increasingly public and creative proposals. Click through the slideshow to see some of our favorite public proposals that have gone viral.
