Here's the longest proposal in planning that we know of. Jack Hyer has always wanted to marry his girlfriend Becca since their first date on September 30, 2010. He embarked on a project to record the longest proposal in making ever.
The video below shows him singing to "I Would Walk 500 Miles" everywhere he traveled over the next four years. From places like Cambodia to Istanbul, to Zanzibar to Mykonos, he documented his travels and after showing Becca the footage, she said yes!
That's some crazy planning. And editing!
