This is what the guy who asked, Portland actor Isaac Lamb, described his amazing stunt, which involved a choreography of 60 people lip-dubbing to a song:
On Wednesday, May 23rd, 2012, I told my girlfriend to meet me at my parent’s house for dinner. When she arrived I had stationed my brother to sit her in the back of an open Honda CRV and give her some headphones. He “wanted to play her a song”…
What she got instead was the world’s first Live Lip-Dub Proposal.
I enjoyed indeed! And his future wife, Amy Frankel, enjoyed it too and said yes!
Crazy people out there, it’s going to be very hard to beat this one (or this other one). But then again, you don’t need crazy stuff to ask someone to marry you. All you need is love. [Thanks Thomas!]
