Isaac's Live Lip-Dub Proposal

Clip description:

"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."

Get a tissue. Get two.

SPAIN: Catalonians Set World Record In Lip-Dub Clip Supporting Independence

From the English portion of the clip description, which is in eight languages:

Lip dub for the independence of Catalonia and the rest of the Catalan Countries, recorded October the 24th 2010 in the city of Vic. Achieving a total amount of 5.771 participants, the World Records Academy awarded the World Record for being the lip dub with highest participation ever. The initiative was born by a group of Catalans, whose aim is to let the whole world know that Catalonia is a nation, and without its independence it cannot be assured its survival and future. The chosen song was composed by the group "Obrint Pas" and its title is "La Flama".
