The only thing worse than these promposal fails is an actual proposal fail. When Bill Devaney asked his longtime girlfriend, Breanne Clark, to marry him, he probs expected her mother to see the beautiful moment. Things didn't exactly goes as planned, as you can see in the video below.

Devaney's original plan was to distract Clark with a family photo while he got down on one knee. Clark's mom wasn't in on this plan, though; in her surprise, she completely face-planted on the beach. Instead of watching her daughter get engaged, she ate sand. :(

"Mom, look up at your daughter right now!" Breanne's sister Bridgett, who uploaded the hilarious moment to YouTube, yells throughout the vid.

"Nothing got hurt on her except for maybe her ego," Bridgett later told BuzzFeed about her mom's ill-timed fall.

Breanne said yes, BTW. And at least her mom (and the rest of the world) can see the heartwarming proposal in all its glory thanks to the internet.
